Overview
All living cells need energy to carry out life processes like growth, repair, and movement. In plants, even though they make their own food using sunlight, they still need to break down that food to release energy. This process is called cellular respiration. It happens in plant cells all the time,
Key Concepts
Glycolysis is the first step
Glycolysis is the first step of cellular respiration and occurs in the cytoplasm. One molecule of glucose (6-carbon) is broken down into two molecules
After glycolysis
After glycolysis, pyruvic acid enters the mitochondria and is converted into acetyl Co-A. This enters the Krebs cycle, a series of reactions that comp
The NADH and FADH2 produced
The NADH and FADH2 produced in earlier steps donate electrons to the electron transport chain located in the inner mitochondrial membrane. As electron
When oxygen is not available
When oxygen is not available, cells carry out fermentation after glycolysis. In plants and yeast, pyruvic acid is converted into ethanol and carbon di
Learning Objectives
