Production of Energy through Cell Respiration

7.1

Production of Energy Through Cellular Respiration

Introduction

Metabolic reaction which are anabolism and catabolism involve energy.
- Catabolism process releases energy.
- Anabolism process uses energy.
Without energy, the anabolic processes such as protein formation which is the basic muscle substance will not occur.

The Main Substrate in Energy Production

Cellular respiration is carried out to generate the energy needed by all living cells.
Cellular respiration is the oxidation process of organic molecules through several stages to release energy.
The main substrate for cellular respiration is glucose.
Chemical energy found in glucose is released to produce energy required by cells.
In humans and animals, glucose is obtained through the digestion of carbohydrates from the food eaten.
In green plants, light energy can be trapped by chlorophyll for the photosynthesis process to produce glucose.

Types of Cellular Respiration

There are two types of cellular respiration, which are aerobic and anaerobic respiration.
Fermentation is an alternative pathway of obtaining energy besides cellular respiration.
