Q. What is the most likely evidence of an energy transformation taking place when a skater glides over ice?
What is the most likely evidence of an energy transformation taking place when a skater glides over ice? Skating blades become cold as kinetic energy is transformed into thermal energy.
Q. What energy transformation occurs when you eat a cookie?
Answer: The correct answer is (A) The chemical energy in the food is converted to mechanical energy to give the body energy to move.
Q. What is the main source of ATP?
Mitochondria are the main site for ATP synthesis in mammals, although some ATP is also synthesized in the cytoplasm. Lipids are broken down into fatty acids, proteins into amino acids, and carbohydrates into glucose.
Q. What are three sources of ATP?
The three sources are ATP already in muscles, ATP made by lactic acid fermentation, and ATP produced by cellular respiration.
Q. Which has more energy ATP or Nadph?
The main difference between ATP and NADPH is that the hydrolysis of ATP releases energy whereas the oxidation of NADPH provides electrons. Furthermore, ATP serves as the main energy currency of the cell while NADPH serves as a coenzyme with the reducing power needed by the biochemical reactions.
Q. What type of metabolic pathway requires oxygen?
Aerobic Glycolysis
Q. Which process results in the highest net production of ATP?
So, oxidative phosphorylation is the metabolic cycle that produces the most net ATP per glucose molecule.
Q. What would yield the highest number of ATP?
The processes of C) oxidative phosphorylation (electron transport chain) would yield the highest number of ATP.
- Oxidative phosphorylation is the metabolic process by which cells use enzymes to oxidize nutrients.
- The process further releases the energy used to generate adenosine triphosphate.
Q. Which part of cellular respiration most efficiently produces ATP?
electron transport chain
Q. What happens if oxygen is absent during the second stage of cellular respiration?
Glycolysis, which is the first step in all types of cellular respiration is anaerobic and does not require oxygen. If oxygen is present, the pathway will continue on to the Krebs cycle and oxidative phosphorylation. However, if oxygen is not present, some organisms can undergo fermentation to continually produce ATP.
Q. What stage of aerobic respiration requires ATP?
Glycolysis
Q. What process breaks down sugars to make ATP when oxygen is available?
Biology A Unit test 3
| Question | Answer |
|---|---|
| Which process breaks down sugars to make ATP when oxygen is present | cellular respiration |
| The part of cellular respiration in which glucose is broken down is called | glycolysis |
| Two products of the Krebs cycle are | ATP and CO-2 |
Q. Which process allows glycolysis to continue in the absence of oxygen?
Fermentation
