Question

question
current cancer research indicates that as some tumours grow, they become deficient in oxygen. how can the cell continue to make atp if oxygen is deficient?
answer
strengthening the proton motive force
increasing the rate of chemiosmosis
i am sure
increasing the rate of glycolysis
shutting down the electron transport chain
i dont know yet

Explanation:

When oxygen is deficient, aerobic respiration (which includes steps like the electron transport chain that rely on oxygen) is affected. Glycolysis is the first step of cellular respiration and can occur in the absence of oxygen (anaerobic conditions). By increasing the rate of glycolysis, more ATP can be produced through substrate - level phosphorylation in glycolysis. Strengthening the proton - motive force and increasing the rate of chemiosmosis are related to aerobic respiration (electron transport chain and oxidative phosphorylation which require oxygen). Shutting down the electron transport chain would further reduce ATP production from aerobic pathways but doesn't address how to make more ATP.

Answer:

increasing the rate of glycolysis
