Question

Myocardium (cardiac muscle tissue) must rhythmically contract for a lifetime. This requires a considerable amount of energy production by the cells. You would expect to see a relatively high amount of which organelle in these cells?

a.smooth endoplasmic reticulum
b.mitochondria
c.lysosomes
d.cytoskeleton

Answer 1

Mitochondria

Step-by-step explanation:

In a cell, the mitochondria is the energy or the powerhouse in a cell responsible of producing energy through respiration.

The mitochondria is has double double membrane.

Myocardium(Cardiac muscle tissue) requires large amount of energy produced by the cell in order to rhythmically contract.

Therefore, it is expected for their cells to have a relatively high amount of mitochondria for the purpose of providing the tissues with energy.
