Camels survive in the desert because they derive water from the large deposit of triglyceridesstored in their humps. How many net moles of water and ATP can be produced from the breakdown ofone mole of the triglyceride, tripalmitoylglycerol, to glycerol and CO2 ? [Don’t forget that ADP + Pi ATP + H2O
The bodies of humans and other mammals store triglycerides in two kinds of tissue, which are called white and brown fat. The main function of white fat is to store triglycerides for energy. Brown tissue has more mitochondria than white tissue, and these are used to generate body heat in an unusual process. Mitochondria in brown fat make thermogenin, a protein that uncouples ATP synthesis from mitochondrial electron transfer chains. Thermogenin is a transport protein that allows hydrogen ions to move directly across the inner mitochondrial membrane instead of through ATP synthase. Since ATP synthase isn't activated, these "leaky" membranes produce less ATP. However, electrons still pass through electron transfer chains, and this process generates heat. In 2015, Daniele Barbato and his colleagues investigated the effect of a high-fat diet on brown fat mitochondrial function in mice. They maintained an experimental group of mice on a high-fat diet (HFD, 60% fat), and a control group…
When fats are used as an energy source, the glycerol portion enters _____ after it has been converted to _______. - The citric acid cycle ; pyruvate - The electron transport system ; coenzyme Q - The citric acid cycle ; acetyle oA - Glycolysis ; fructose-6-phosphate - Glycolysis ; dihydroxyacetone phosphate
A new energy drink in stores contains no sugar, carbs or fat. It does, however, contain relatively high concentrations of B-vitamins (B-3, B-5, B-6, and B-12) which our digestive system does not break down. If our useable energy (ATP) is supplied by cellular respiration, where would the energy this products claims to provide come from?
What happens to the ATP made during glycolysis and the citric acid cycle? It is used to drive cellular reactions. It is used to drop off electrons into the electron transport chain. It is used to drive the formation of acetyl-CoA. It is not used by the cell.
Fatty acids are broken down toa. pyruvate molecules, which take electrons to the electrontransport chain.b. acetyl groups, which enter the citric acid cycle.c. amino acids, which excrete ammonia.d. glycerol, which is found in fats.e. All of these are correct.
Which of the following substances ATP, CoA-SH, FAD and NAD+ have the subunits in their structure? A.Have 2 two ribose subunits.B.Have two phosphate subunits.C.Has a single adenine subunitD.Have four different types of subunits.
Lauric acid is a 12-carbon fatty acid with no double bonds. The sodium salt of lauric acid (sodium laurate) is a common detergent used in a variety of products, including laundry detergent, shampoo, and toothpaste. How many molecules of ATP and NADPH are required to synthesize lauric acid?
Which of the following pair of substances are products of the citric acid cycle? a) Acetyl CoA and NADH b) Acetyl CoA and CO2 c) CoA-SH and FADH2 d) Citrate and CO2
how many cycles are necessary to break down a molecule of glucose into CO2
Each ATP molecule contains about 1% of the amount of chemical energy available from the complete oxidation of a single glucose molecule. Cellular respiration produces about 38 ATP from one glucose molecule. What happens to the rest of the energy in glucose? It is stored as fat. It is converted to heat. It is used to make water from hydrogen ions and oxygen. It is released as carbon dioxide and water It is converted to starch.
Glycogen is not as reduced as fatty acids are and consequently are not as energy rich. Why isn’t all excess fuel stored as fatty acids rather than as glycogen?
