What are the 4 steps of cellular respiration?

1. Glycolysis


2. Acetyl- Coast


3. Citric Acid Cycle


4. Electron Transport Chain

What are the 2 ways of making ATP?

1. Substrate level phosphorylation: ATP is made from ADP, during glycolysis and citric Acid cycle


2. Chemiosmosis: proton gradient is made

What is oxidation?

Loss of an electron

What is cellular respiration?

The breaking down of carbohydrates, lipids, and proteins.

What is reduction?

A gain in electrons

What happens in Glycolysis?

Glucose is broken down into 2 pyruvate , 2 ATP and 2 NADH. Uses substrate level phosphorylation

What is the mitochondria matrix?

Space inside the inner membrane

What happens in Acetyl CoA synthesis?

Pyruvate is broken down to release energy/ oxidized. CO2 is let off.

What happens in the citric Acid cycle?

Acetyl CoA bonds are converted to ATP by substrate level phosphorylation. Results in 1 ATP, 6NADH, 2FADH2, And 4 CO2

What drive ATP synthase?

A proton gradient composed of 2 subunits F0 and F1

What is glucose stored as in animals?

Glycogen

What is glucose stored as in plants?

Starch

Phosphofructokinase

Gives feedback of each step

Where does Acetyl CoA occur?

Mitochondria

Where does the Citric Acid cycle occur?

Mitochondria matrix
