Anatomy & Physiology Question #1

Question

The nurse is reviewing the structure of a cell to help understand a patient’s disease process. Which organelle should the nurse identify that in most cells produces energy and respiration?

Overview

Explanation

The correct answer is A. The mitochondria is an organelle found in large numbers in most cells. This is where the biochemical processes of respiration and energy production occur. The mitochondria has a double membrane, the inner layer being folded inward to form layers (cristae). Energy and respiration are not produced in the lysosomes, or the smooth or rough endoplasmic reticulum.
