Question

From the blood and glycogen stored in skeletal muscle cells, what can be used to produce ATP by aerobic and anaerobic cellular respiration?

1) Blood only
2) Glycogen only
3) Both blood and glycogen
4) Neither blood nor glycogen

Answer 1

Glycogen and glucose from blood can both be used to produce ATP through aerobic or anaerobic cellular respiration, hence the correct answer is that both blood and glycogen are used.

Step-by-step explanation:

The substances from blood and glycogen stored in skeletal muscle cells that can be used to produce ATP by aerobic and anaerobic cellular respiration are both blood and glycogen. Glycogen stored in muscle cells can be broken down into glucose, which is then used in glycolysis to produce ATP and pyruvate. Pyruvate is then used to produce ATP in aerobic respiration when oxygen is available, or it is converted into lactic acid during anaerobic respiration when oxygen is not available.

Similarly, glucose circulating in the bloodstream can also be used in glycolysis, followed by the aerobic respiration pathway to generate ATP. Consequently, the correct answer is 3) Both blood and glycogen.
