a. Sun (solar energy)

b. Plants use solar energy to make​ food

c. Plants use plant food for : cellular energy = ATP (chemical energy)

d. Animals eat plants or animals ​for purpose of creating ATP ( chemical energy.)

​

Energy Sources:

Type Description Example

Autotrophs or Organisms that make their own food:​ Plants

Producers

​

​

Heterotrophs or Organisms that obtain energy from the food they eat (ATP​) Animals

​Consumers

​

Types of Organisms:

is the chemical reactions in the body's cells that change food into energy

Metabolism

Anabolism and catabolism are the two broad types of biochemical reactions that make up metabolism. Anabolism builds complex molecules from simpler ones, while catabolism breaks large molecules into smaller ones.

Catabolic / Anabolic

1. Cell division

2. Active transport

3. Movement

4. Making Molecules

5. Maintain homeostasis

Cells need energy for:

​

1. Adenine (Nitrogenous base)

2. Ribose (sugar)

3. 3 Phosphate Groups

Three phosphates bonded together by covalent bonds (phosphate bond)

​

Cellular Energy ATP: Adenosine TriPhosphate:
