Aerobic and Anaerobic Cellular Respiration

lodenquai makes me wanna kms

Cellular Respiration definition

Cell process where the the energy in nutrients is converted to ATP.

Glycolysis definition

First stage of anaerobic AND anaerobic cellular respiration. Breaks glucose down into two pyruvates and making 2 ATP.

ATP

Adenosine triphosphate. Cellular Energy.

Pyruvate

3 carbon sugar produced when glucose is split during glycolysis

Mitochondria

Organelle found in all organisms that is the site of aerobic cellular respiration

Krebs Cycle

Pyruvate from glycolysis is broken down in the mitochondria releasing CO2 and producing NADH, FADH2, and 2 ATP.

Electron Transport Chain

Step of aerobic respiration that take the high energy electrons from the Krebs cycle to change ADP to ATP. 34 ATP is made

Anaerobic Respiration

Does not use oxygen

Aerobic Respiration

Uses oxygen

Fermentation

When oxygen is NOT present in anaerobic cellular respiration and cells make EITHER lactic acid or alcohol.

Cytoplasm

site of glycolysis

Cellular Respiration Chemical Equation

C6H12O2 + 6O2 ------> 6CO2 + 6H20 + Energy (ATP)

34

Amount of ATP made in the Electron Transport System (ETS).

4

Amount of net ATP made during glycolysis and the kreb's cycle.

NADH

Electron carrying molecule produced in the Glycolysis and the Kreb's cycle.

FADH2

Electron carrying molecule made during the Kreb's cycle

CO2

This gas is produced during the Kreb's cycle as Acetyl CoA is broken down.

Lactate

product of fermentation in animals and some bacteria.

ethyl alcohol

product of fermentation in fungi and plants

38

amount of ATP broken down from 1 sugar molecule during the 3 step process of aerobic cellular respiration.

Lactic acid fermentation

the chemical breakdown of carbohydrates that produces lactic acid as the main end product

Alcoholic fermentation

A process used by yeast cells and some bacteria breakdown glucose into carbon dioxide and ethyl alcohol

Link Reaction

Step of respiration which occurs in the matrix of the mitochondria, where pyruvate are split into a 2 carbon molecule called Acetyl CoA

Fermentation

A catabolic process that makes a limited amount of ATP from glucose and produces a characteristic end product, such as ethyl alcohol or lactic acid.
