The red blood cells require ATP in order to maintain ion gradients across their membrane. In the absence of these ion gradients, the red blood cells will swell and burst, bringing about a hemolytic anemia. Red cells generate their energy via which one of the following? A. Electron transfer to oxygen B. TCA cycle C. Substrate-level phosphorylation D. Oxidative phosphorylation E. Oxidation of glucose to CO2 and H2O
Understand the Problem
The question is asking about the mechanism through which red blood cells generate energy, specifically in the context of maintaining ion gradients and preventing hemolytic anemia. The user needs to select the correct metabolic pathway or process related to energy production.
Answer
Substrate-level phosphorylation.
The final answer is C. Substrate-level phosphorylation.
Answer for screen readers
The final answer is C. Substrate-level phosphorylation.
More Information
Red blood cells generate ATP through glycolysis, as they lack mitochondria for oxidative phosphorylation.
Tips
Remember that red blood cells do not have mitochondria, preventing them from using methods involving the electron transport chain.
