Why is it important that cardiac tissue contain many mitochondria and capillaries?
A)Cardiac tissue primarily uses mitochondria for fermentation to generate ATP and capillaries provide a way to get rid of the lactic acid.
B)Cardiac tissue primarily uses mitochondria for anaerobic respiration to generate ATP and capillaries get rid of the waste generated.
C)Cardiac tissue primarily uses mitochondria for glycolysis to generate ATP and capillaries provide the oxygen and nutrients for this process.
D)Cardiac tissue is metabolically active and dependent on mitochondrial activity to use aerobic respiration to generate ATP and capillaries provide the oxygen and nutrients for this process.
E)Cardiac tissue is metabolically active and dependent on the mitochondrial activity for the breakdown of fatty acids during beta-oxidation and the capillaries provide the fatty acids for this process.

Question

Quizplus · Accepted Answer

Cardiac tissue is constantly active and in need of ATP to sustain muscle contraction. This ATP is primarily generated through aerobic respiration in the mitochondria. Therefore, the presence of many mitochondria in cardiac tissue is important for meeting the high energy demands of the heart. Capillaries are also important to deliver oxygen and nutrients to the mitochondria for the process of aerobic respiration. Additionally, cardiac tissue has a high demand for nutrients and oxygen due to its constant activity, and the presence of many capillaries ensures that these needs are met.
