Question

question 25
a scientist observed that during the course of a chemical reaction in a tissue culture of animal muscle cells, the number of atp molecules produced was greatly reduced. what did the scientist most likely hypothesize from the observation?
o a oxygen availability became limited
o b oxygen availability increased
o c carbon dioxide availability increased
o d carbon dioxide availability became limited

Explanation:

ATP is mainly produced through aerobic respiration in animal cells, which requires oxygen. If ATP production is greatly reduced, it is likely due to limited oxygen availability. Increased oxygen would promote more ATP production. Carbon dioxide is a by - product of respiration and its availability (increase or limitation) does not directly cause a large reduction in ATP production in the context of normal cellular respiration processes in animal muscle cells.

Answer:

A. oxygen availability became limited
