Overview

Notice how one body depends on food, oxygen, transport, control, and cell division at the same time. Energy comes from carbohydrates, fats, and proteins, and mitochondria harvest that energy in cells. Count the links carefully: digestion supplies nutrients, respiration releases ATP, circulation carr

Key Concepts

Living organisms need a continuous supply

Living organisms need a continuous supply of energy for body functions. Food and oxygen are carried to cells through the circulatory system, and mitoc

Glycolysis is the first step

Glycolysis is the first step of both aerobic and anaerobic respiration. It occurs in the cytoplasm and converts glucose into pyruvic acid with formati

Krebs cycle

Krebs cycle, also called the tricarboxylic acid cycle or citric acid cycle, is the second step of aerobic respiration. It occurs in mitochondria and o

This is the third step

This is the third step of aerobic respiration and occurs only in mitochondria. It uses NADH2 and FADH2 to make ATP and water. Each NADH2 gives 3 ATP a

ATP is an energy

ATP is an energy-rich triphosphate molecule made from adenosine, ribose sugar, and three phosphate groups. Energy is released when the phosphate bond
