Carbohydrates and fat are considered high energy foods because they provide a large source of energy without providing anyearchers for energy. They are considered one of the most important eatables because of their ability to help you lose weight and maintain a healthy weight. However, you can get the best out of your weight loss and fitness goals by using your own choice of vegetables, fruits, and whole grain bread or pasta to make your own high energy foods.
The large amount of sugar and carbohydrates that are found in high energy foods can lead to weight gain. When used in place of real food, sugar and carbohydrates can lead to an over-the-counter medication calledropidio10. This will give you aCommercial for $0.70 per day.

Why are carbohydrates and fats frequently considered high energy foods quizlet?
Carbohydrates and fats are frequently considered high-energy foods because they contain many electrons associated with hydrogen atoms. This free energy for the oxidation of glucose to CO2 and water is -686 kcal/mol and the free energy for the reduction of NAD+ to NADH is +53 kcal/mol.
How many carbon atoms are fed into the citric acid cycle as a result of the oxidation of one molecule of pyruvate?
In the oxidation of pyruvate to acetyl CoA, one carbon atom is released as CO However the oxidation of the remaining two carbon atoms to acetate requires a complex eight-step pathway. The citric acid cycle is the process that provides energy for the body.
Why is glycolysis described as having an investment phase and a payoff phase?
In the presence of oxygen the three-carbon compound pyruvate can be catabolized in the citric acid cycle.
Why do fats supply more energy than carbohydrates when they are metabolized?
When the greater number of electrons around the carbon atoms in fatty acids are transferred to oxygen, more energy is released than when the same process happens to carbohydrates.
Why are carbohydrates and fats considered?
The body uses three main nutrients to function. These nutrients are carb, protein, and fat. These nutrients are digested into simpler compounds.
Which molecule is metabolized in a cell to produce energy currency in the form of ATP?
The process of cellular respiration can metabolize one molecule of glucose into 30 to 32 ATP. The process of glycolysis only produces two ATP while all the rest are produced during the electron transport chain.
How is cellular respiration different from breathing?
Cellular respiration involves the production of energy by breakdown of glucose whereas breathing involves taking in oxygen and removing carbon dioxide from the body and feeling effects of carbon dioxide in the air.
Why is glycolysis considered to be one of the first metabolic pathways to have evolved?
Glycolysis is considered one of the first metabolic pathways to have evolved because it relies on chemiosmosis, which is a metabolic mechanism present only in the first cells.
What energy intermediates are produced in the citric acid cycle?
Alpha-ketoglutarate (HKG) and fumarate (FUM) are all intermediates of the citric acid cycle. Acetyl-CoA can come from various metabolic pathways including glycolysis (and subsequent pyruvate dehydrogenation) and beta-oxidation of fatty acids.
What are the net energy products for each turn of the citric acid cycle?
The citric acid cycle is a series of redox dehydration hydration and decarboxylation reactions. Each turn of the cycle forms one GTP or ATP as well as three NADH molecules and one FADH2 molecule. These molecules are used in further steps of cellular respiration to produce ATP for the cell.
How did the fat leave her body?
The byproducts of fat metabolism leave your body: As water through your skin and your kidneys. As carbon dioxide through your lungs when you breathe out.
Why is the energy investment phase of glycolysis necessary?
This phase is known as the energy-requiring phase or the energy investment phase because energy in the form of ATP is needed in order to form the unstable fructose molecule from glucose.
Why must two ATP be used during the energy investment phase?
The first and third steps of glycolysis are both energetically unfavorable. This means they will require an input of energy in order to continue forward. Per glucose molecule 1 ATP is required for each of these steps. Therefore, a total of 2 ATP is needed during the energy investment phase of glycolysis.
Why does fat produce more energy?
Fats have more energy than carbohydrates and proteins. This is because of the oxidation rate of the reaction to convert fats to carbon dioxide and water.
Why do fats have the most energy?
When broken down, Fats give more energy.The length of the carbon chain is variable, it can be as small as 3 carbons and as long as 38 carbons. They can have only single bonds called saturated fatty acids or they can have double bonds which are then called unsaturated fatty acids.
Do fats produce more energy than carbohydrates?
Fats are the slowest source of energy, but the most energy-efficient form of food is Fats are the slowest source of energy, but the most energy-efficient form of food is protein and carbohydrates.
Why carbohydrates are called energy giving food?
Carbohydrates are the body’s main source of fuel. They are easily converted into energy.
Does fat provide energy?
Fats give you energy and they help the body absorb certain vitamins. Essential fatty acids help the body function but they aren’t made by your body. Many foods naturally contain fats including dairy products meats poultry seafood and eggs and seeds nuts avocados and coconuts.
Which molecule is metabolized in a cell to produce energy?
The following terms are used in this set:
The following set of Terms is used in this set:
Which of the following makes the most energy in the form of ATP?
The electron transport chain is a sequence of electrons going from left to right in a alpha configuration.This stage produces most of the energy for most of the cycle. The electron transport chain takes place in the mitochondria.
Which of the following produces a significant amount of energy in cellular respiration?
The main chemical produced in cellular respiration is ATP. ATP is the standard unit in which the energy released during respiration is stored.
Why do we deep breath after exercise?
Your body uses more oxygen and produces more carbon dioxide when you exercise and your muscles work harder. To cope with this extra demand your breathing has to increase from about 15 times a minute (12 litres of air) when you are resting up to about 40\u201360 times a minute (100 litres of air) during exercise.
Why are sweating and other body cooling mechanisms necessary?
The body’s sweating mechanisms are necessary because oxygen is very electronegative – making it very powerful in pulling electrons down the electron transport chain.
Why does an athlete breathe faster after finishing a race?
During the run, the energy demand is high but the oxygen supply to produce energy is limited. Therefore, an athlete breathes faster and deeper than usual after finishing the race to provide extra oxygen and hence extra energy to the body.
Why is glycolysis considered the most primitive ancient energy converting process?
The process of glycolysis is considered to be an ancient metabolic process because it does not require oxygen. Glycolysis is a process that helps the body to obtain energy from starch and glycogen. To obtain energy from these materials, the body must begin by processing them into ATP.
In what Bonds is the chemical energy stored in fats and carbohydrates?
There are two ways that living organisms store energy: Energy-rich molecules: Glycogen carbohydrates triglycerides and lipids are energy storage molecules.
Major ways that living organisms store energy:
1. Glycogen carbohydrates triglycerides and lipids are energy storage molecules. In fact any biologically synthesised molecules like proteins serve as energy storage.
2. There are two major ways that living organisms store energy: Energy-rich molecules: Glycogen carbohydrates triglycerides and lipids are energy storage molecules. In fact any biologically synthesised molecules like proteins serve as energy storage.
How is glycolysis considered a metabolic pathway?
Glycolysis is the process of degradation of glucose into pyruvate and energy used to form adenosine triphosphate (ATP) and reduced nicotinamide adenine dinucleotide (NADH).
What are energy intermediates?
The energy is transferred from molecules such as glucose to an intermediate energy source such as ATP. ATP is a reservoir of potential chemical energy and acts as a common intermediate in metabolism.
What happens to excess energy that is released from the metabolism of glucose?
The enzymes of the Krebs cycle work in the cytosol of bacteria but among eukaryotes the enzymes work mostly in the mitochondria.
Why does fermentation produce less ATP than aerobic respiration?
Aerobic respiration is the process by which organisms break down glucose to produce ATP. Fermentation produces relatively less energy than respiration because there is no complete oxidation of glucose.
