Lesson 3 - Cell Metabolism

Introduction
 

Getting Started

"Living things cannot maintain their organization or carry on life's other activities without a source of organic nutrients. Nutrient molecules are used by organisms as a source of energy and cellular building blocks. The term metabolism encompasses all the chemical reactions that occur in a cell. Enzymes are protein molecules that speed metabolic reactions in cells."


Focus on Learning
Reading Assignment
 
Use the course competencies listed below to focus your learning and use the lesson objectives to sharpen that focus.
 
Competencies By the end of the lesson , you should be able to:

  1. Describe principles of cell metabolism and energy utilization.
 
Objectives

To master the competencies, you should seek to understand how:

  1. The breakdown of ATP can be coupled to reactions that require an input of energy.
  2. Energy from glucose breakdown drives ATP buildup.
  3. Cells have metabolic pathways in which every reaction has a specific enzyme.
  4. Enzymes speed reactions.
  5. Reactant concentration affects speed of reaction.
  6. Enzironmental factors affect enzyme activity.
  7. Oxidation-reduction reactions make energy available to living things.
