Cellular Respiration and Fermentation

Cellular Respiration

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

Autotroph

organisms that make their own food

Heterotroph

.need to eat other organisms to get their food

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 releasing CO2 and producing 6 NADH, 1 FADH2, and 1 ATP.

Electron Transport Chain

Step of aerobic respiration that take the high energy electrons from the Krebs cycle to change ADP to ATP. 30-34 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.

Glycolysis

The first step of cellular respiration

Cytoplasm

Place where cells perform glycolysis

Krebs Cycle and Electron Transport Chain

Processes occurring in the Mitochondria

Steps 2 and 3 of Cellular Respiration.

Definition of Cellular Respiration

The process of breaking the chemical bonds of glucose into energy.

Cellular Respiration Chemical Equation

C6H12O6 + 6O2 ------> 6CO2 + 6H20 + Energy (ATP)

30-34

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

4 (2 net)

Amount of ATP made during glycolysis.

NADH

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

CO2

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

ATP

This energy molecule is made in all three stages of cellular respiration. Adenosine triphosphate.

Inner Membrane

The location of the electron transport system.

Lactate

product of fermentation (in animals and some bacteria)

ethyl alcohol

product of fermentation (in fungi and plants)

Only lactic acid fermentation

Found in the body after doing exercises like plank and wall sits

Only alcoholic fermentation

Yeast when fed glucose produce CO2 (carbon dioxide)

30-38

Total amount of ATP made in cellular respiration
