What are the sources of energy for living things?

Food

1

Autotroph

Organism that can make its own food, therefore receiving energy

2

Heterotroph

Organism that relies on another organism for energy

3

How do heterotrophs indirectly use the suns energy?

They eat organic molecules, in which the suns energy is stored in these molecules

4

Relationship between glucose and ATP

Food is broken down into glucose, and glucose is broken down into ATP, which is the cell can use for energy

5

Esophagus

Food channel to the stomach

6

Stomach

Stores food

7

Liver

Filters blood, converts nutrients to energy

8

Gallbladder

Stores bile

9

Pancreas

Sends digestive juices to intestines

10

Small intestine

Absorbs nutrients into the bloodstream

11

Large intestine

Absorbs water

12

Aerobic

With air

13

Anaerobic

Without air

14

What is the role of the mitochondria in cellular respiration?

The Krebs cycle and the electron transport chain take place in the mitochondria

15

Where does glycolysis take place?

In the cytoplasm

16

What does glycolysis break down?

Glucose

17

Glycolysis

Use 2 ATP to break down glucose to pyruvate, producing 4 molecules of ATP

18

In glycolysis what is the net ATP gain?

2 ATP

19

Krebs cycle

Break down pyruvate producing 2 ATP, and CO2 as waste

20

Electron transport chain

Uses high energy electrons transported by electron carries NADH and FADH2 to convert ADP to ATP

21

How much ATP does the electron transport chain produce?

32 ATP

22

How much ATP does cellular respiration produce?

36 ATP

23

Energy

The ability to do work

24

Ingestion

Taking food into your body

25

Digestion

The process of breaking down food into glucose molecules to be used in cellular respiration

26

ATP

One of the most important compounds cells use to store and release energy

27

ATP structure

Adenine, ribose, and three phosphate groups

28

How does ATP release energy?

By breaking down and reforming the bonds between its phosphate groups. This makes ATP very useful as a basic energy source for all cells

29

Calorie

Unit of energy
