New cards

Describe the flow of energy

The movement of energy in a linear function within an ecosystem, where compounds cycle between photosynthesis and cellular respiration.

2
New cards

Ecosystem

A system consisting of living and nonliving things, with the sun as the main source of light.

3
New cards

Photosynthesis

The process that converts sunlight into organic molecules and oxygen as waste, fueling cellular respiration.

4
New cards

Cellular respiration

The process that uses the waste products of photosynthesis as fuel to produce ATP for cellular work, with carbon dioxide and water as waste.

5
New cards

Heat energy

Energy that cannot be recycled within an ecosystem.

6
New cards

Entropy

The generation of waste energy and waste products in cellular respiration, leading to an increase in disorder.

7
New cards

Simplified chemical formula for cellular respiration

The equation representing the conversion of oxygen and glucose into carbon dioxide and water, releasing energy.

8
New cards

Coupling reactions

The process of converting ADP and Pi into ATP, using energy from glucose to create potential and chemical energy.

9
New cards

Redox reactions

Reactions involving oxidation (loss of electrons) and reduction (gain of electrons), performed by dehydrogenase.

10
New cards

Phosphorylation

The process of adding a phosphate group to a chemical.

11
New cards

Substrate level phosphorylation

Phosphorylation that occurs when a phosphate group from an organic molecule is transferred to another organic molecule.

12
New cards

Oxidative phosphorylation

Phosphorylation that occurs when a chemical gains a phosphate group using energy from the oxidation of another chemical.

13
New cards

Glycolysis

The process that converts glucose into two pyruvates, producing ATP and NADH.

14
New cards

Linkage reaction

The step between glycolysis and the Krebs cycle, producing CO2 and NADH.

15
New cards

Krebs cycle

The cycle that traps energy from Acetyl CoA in NADH, FADH2, and ATP.

16
New cards

Electron carriers

NADH and FADH2, which transport electrons in the Krebs cycle.

17
New cards

Electron Transport Chain

The process that uses electron carriers to produce ATP through oxidative phosphorylation.

18
New cards

Poisons

Substances that interfere with the electron transport chain and ATP production.

19
New cards

Fermentation

The process of producing energy in the absence of oxygen, either through lactic acid or alcohol fermentation.
