Question
Chapter 4, Problem 6aCP
Summary Introduction
To review:
The following:
1. The description of the first and the second law of
2. The process used by cells to obtain this energy.
Introduction:
Thermodynamics is regarded as the branch of physics that states the relationship between heat and other forms of energy. It explains how thermal energy is transformed into other forms of energy and its effects on matter. Glucose is the carbohydrate molecule used by most of the cells in the body to obtain energy.
