Chapter 3, Problem 7WIO

Summary Introduction

To determine:

A cell which can efficiently exchange gas and metabolize sugar. Tell the shape, size and organelles in abundance.

Concept introduction:

Metabolism of sugar (carbohydrates) happens partly in the cytosol and partly in the mitochondria. The part happening in the cytosol is called glycolysis and the part in mitochondria consists of citric acid cycle and oxidative phosphorylation. In the whole process glucose is broken down to release CO₂ and make ATP molecules in the presence of oxygen.
