1

Energy

The ability to do work

2

Thermodynamics

The study of the flow and transformation of energy in the universe

3

Metabolism

All of the chemical reactions in a cell

4

Photosynthesis

The anabolic pathway in which light energy from the Sun is converted into chemical energy for use by the cell

5

Cellular Respiration

The catabolic pathway in which organic molecules are broken down to release energy for cell use

6

Adenosine triphosphate

The most important biological molecule that provides chemical energy

7

Thylakoids

Flattened, saclike membranes that are arranged in stacks; where light-dependent reactions take place

8

Grana

The stacks in Thylakoids

9

Stroma

The fluid-filled space outside the Grana

10

Pigments

Light-absorbing molecules found in the thylakoid membranes of chloroplasts

11

NADP+

Molecules that transport electrons during photosynthesis

12

Calvin Cycle

Second phase of photosynthesis where energy is stored in organic molecules such as glucose; light-independent reaction

13

Rubisco

Enzyme that converts inorganic carbon dioxide molecules into organic molecules during the final step of the Calvin cycle

14

Anaerobic process

Metabolic process that does not require oxygen

15

Aerobic process

A metabolic process that requires oxygen

16

Aerobic respiration

Metabolic process in which pyruvate is broken down and electron-carrier molecules are used to produce ATP through electron transport

17

Glycolysis

Process where glucose is broken down in the cytoplasm

18

Krebs cycle

The series of reactions in which pyruvate is broken down into carbon dioxide

19

Fermentation

Process in which NAD+ is regenerated, allowing cells to maintain glycolysis in the absence of oxygen
