1

Metabolism

The sum of all chemical reactions in an organism.

New cards
2

Potential Energy

Stored energy that has the potential to do work.

New cards
3

Kinetic Energy

The energy of motion; energy that is actively being used.

New cards
4

First Law of Thermodynamics

Energy cannot be created or destroyed, only transformed from one form to another.

New cards
5

Second Law of Thermodynamics

Energy transfer increases the entropy of a system.

New cards
6

Entropy

A measure of disorder or randomness in a system.

New cards
7

Metabolic Pathways

Series of chemical reactions occurring within a cell.

New cards
8

Endergonic Reaction

A reaction that absorbs energy from its surroundings.

New cards
9

Exergonic Reaction

A reaction that releases energy to its surroundings.

New cards
10

ATP (Adenosine Triphosphate)

The primary energy carrier in all living organisms.

New cards
11

Phosphorylation

The addition of a phosphate group to a molecule, often used in energy transfer.

New cards
12

Enzymes

Proteins that act as catalysts to speed up chemical reactions in a cell.

New cards
13

Activation Energy

The minimum amount of energy required to start a chemical reaction.

New cards
14

Redox Reactions

Chemical reactions that involve the transfer of electrons between two species.

New cards
15

Glycolysis

The breakdown of glucose into pyruvate, producing a small amount of energy.

New cards
16

Fermentation

Anaerobic process that converts sugars to acids, gases, or alcohol.

New cards
17

Photosynthesis

The process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water.

New cards
18

Chlorophyll

The green pigment found in plants that is essential for photosynthesis.

New cards
19

Photoautotroph

Organisms that use light energy to convert carbon dioxide and water into glucose.

New cards
20

Calvin Cycle

Light-independent reactions in photosynthesis that convert CO2 into glucose.

New cards
21

C3 Plants

Plants that use the Calvin Cycle for the first step of carbon fixation.

New cards
22

C4 Plants

Plants that use an alternative pathway for carbon fixation, allowing for greater efficiency in hot climates.

New cards
23

CAM Plants

Plants that fix carbon at night to reduce water loss.

New cards
24

Stomata

Small openings on the surfaces of leaves that allow gas exchange.

New cards
25

ATP Synthase

An enzyme that creates ATP using a proton gradient.

New cards
26

Oxidative Phosphorylation

The production of ATP using the electron transport chain and chemiosmosis.

New cards
27

Chemiosmosis

The movement of ions across a selectively permeable membrane, driving ATP synthesis.
