Chapter 22, Problem 49P

Interpretation Introduction

Interpretation:

The reason should be explained for the muscle weakness in people deficient with carnitine acyltransferase II.

The reason for more severe symptoms during fasting must be determined.

Concept introduction:

The molecules and ions move across the membranes by two systems, active transport system, and passive transport system. The passive transport allows the molecules to move across the membrane down their concentration gradient, while active transport allows the molecules to move against their concentration gradient. The active transport process requires energy in the form of ATP.
