Question

1. energy is

eleased\ when adp gains a phosphate.
a. true
b. false

1. the part of the atp molecule used for energy storage is the

a. high energy bond
b. phosphate group
c. ribose
d. adenine

1. in which organelle is energy released and atp made/recycled?

a. mitochondrion (singular for mitochondrial
b. chloroplast
c. ribosome
d. none of the above

1. atp is called a cells \energy currency\ because

a. atp catalyzes all metabolic reactions.
b. atp allows one organelle to be exchanged for another between cells.
c. the energy that drives cellular processes is supplied by atp.
d. glucose is made of atp.

1. which process produces more atp?

a. aerobic respiration
b. anaerobic respiration

1. which two steps of cellular respiration take place in the mitochondria?

a. glycolysis and krebs cycle
b. glycolysis and etc
c. krebs cycle and etc

1. which step of cellular respiration happens for both anaerobic and aerobic respiration?

a. electron transport chain
b. krebs cycle
c. glycolysis
d. none of these

Explanation:

1. When ADP gains a phosphate to form ATP, energy is stored, not released.
2. The high - energy bond in ATP is used for energy storage.
3. Mitochondria are the powerhouses of the cell where energy is released and ATP is made/recycled.
4. ATP is called the cell's energy currency because the energy that drives cellular processes is supplied by ATP.
5. Aerobic respiration produces more ATP than anaerobic respiration.
6. The Krebs cycle and ETC (electron transport chain) take place in the mitochondria.
7. Glycolysis is the first step of cellular respiration and occurs in both aerobic and anaerobic respiration.

Answer:

1. B. False
2. A. High energy bond
3. A. Mitochondrion (singular for mitochondrial)
4. C. The energy that drives cellular processes is supplied by ATP
5. A. aerobic respiration
6. C. Krebs cycle and ETC
7. C. Glycolysis
