When the swimmer is unable to take in enough oxygen for the sprint, the ATP (Adenosine triphosphate) will be compromised. In such conditions, the body will use anaerobic respiration to produce the ATP. Anaerobic respiration takes place in the absence of oxygen. It used the electron acceptors in place of the oxygen in the respiratory cycle. The amount of the ATP produced is, however, less in anaerobic respiration.
Hence, the answer is 'Option C - Anaerobic respiration would be used to produce small amounts of ATP in the absence of oxygen'.
People who have leukemia, a cancer that affects white blood cells, are often given Cytrabine. This drug inhibits the synthesis of DNA.
S-phase of cell cycle is most affected by Cytrabine because cytrabine interfers with synthesis of DNA and we know that in S-phase of cell cycle synthesis of DNA takes place.
Semipermeable means the cell membrane can pick and choose what goes out of it and into it. At least, that's what I believe it is.
