Question

Why do cancer cells rely so much on metabolism of glucose ? 1 point) Because cancer cells grow in an anaerobic environment Because cancer cells display increased oxidative phosphorylation. To regenerate NADH. To synthesize small molecule building blocks and membranes required for cell growth. Because cancer cells have decreased protein synthesis.

Answer 1

Answer:

(a) Because cancer cells grow in an anaerobic environment

Explanation:

Cancer cells grow in an anaerobic environment so they cannot use the usual oxidative phosphorylation. They use the last compound generated through glycolysis (pyruvate), convert it to lactate, and start the lactate pathway. Even in conditions with high oxygen concentration, cancer cells do this, and it is thought that it is because they have some damage in mitochondrial activity but it is not proved, this is called the Warburg effect.
