Cellular respiration

Homeostasis

The state of something being balanced and regulated, getting what we need

Cellular respiration

A metabolic process where glucose to convert it into energy or adenosine triphosphate

Average ATP needed per day

100 pounds

Aerobic organisms

Organisms that need oxygen to live

Anaerobic respiration

Doesn’t need oxygen

Fermentation

The process of breaking down sugars without oxygen

Cellular respiration equation

C6H12O6 + 6O2 = 6CO2 + 6H2O + ATP

Photosynthesis equation

6H2O + 6CO2 + LIGHT = C6H12O6 + 6O2

Glycolysis

Takes place in the cytoplasm without needing any oxygen. 6C glucose molecules are broken down into 2 pyruvate molecules per 3C. The net gain is 2 ATP and 2 NADH + 2 pyruvate

Krebs cycle / citric acid

An aerobic process in the mitochondrial matrix. The two pyruvate is converted into 2 ACETYL-COA, producing 4 CO2, 2 ATP, 6 NADH, 2 FADH2 per glucose

Electron transport chain & chemiosmosis

Aerobically happens in the inner mitochondrial chain (cristae). 32-34 ATP and 6H2O is produced

Final ATP yield per 1 glucose

2 (G) + 2 (K) + 32-34 (E) = 36-38 ATP

Total input

1 glucose + 6O2 + 10NAD+ + 2FAD + 36-38 ADP + P

Total output

2FADH+ + 36-38 ATP + 6H2O + 6CO2 + 10NADH

What is the linking reaction?

It connects glycolysis to the krebs cycle

What do you use pyruvate for?

2 pyruvate is used to make 2 ACETYL-COA

What are the 2 ACETYL-COA molecules used for?

It is used to make 2 ATP, 2 NADH, 2 FADH2, 4 CO2

Where does majority of the ATP come from?

From the ETC, where 32-34 ATP is made and 6H2O

How many carbon in one glucose?

6

How many Carmina in pyruvate?

3

How many carbons in 1 ACETYL COA?

2

Does the pyruvate oxidation to become Acetyl-CoA happen in glycolysis, link reaction, or Krebs cycle itself?

In the link reaction, mitochondrial matrix

Where does pyruvate oxidation (conversion to acetyl-CoA) occur?

Mitochondria matrix
