Presentation Transcript
what are the 5 stages of aerobic cellular respiration
What Are the 5 Stages of aerobic cellular respiration?
  • 1. Glycolysis
  • 2. Oxidation Of pyruvate to Acetyl CoA
  • 3. Krebs Cycle
  • 4. Electron Transport Chain
  • 5. Chemiosmosis
what do both aerobic and anaerobic cellular respiration have in common
What do both aerobic and anaerobic cellular respiration have in common?
  • Both run the process of Glycolysis outside of the mitochondria.
  • Both have a net yield of 2 ATP
what do you need to know about glycolysis
What do You Need to know about glycolysis?

- What is the starting reactant in Glycolysis?

Glucose

- How much ATP is needed in glycolysis, and how much ATP is made Net and Gross amounts?

Needed= 2 ATP

Gross= 4 ATP

Net= 2 ATP

anaerobic respiration
Anaerobic Respiration

Anaerobic Respiration

Yields 2 lactate or 2 ethanol

Requires Glucose

Produces water

Net 2 ATP

No Oxygen

Requires Oxygen

Net 36 ATP

Uses Glycolysis

what is important about stage 2 in aerobic cellular respiration
What is Important about Stage 2 in Aerobic Cellular Respiration?

What Is Needed to start the reaction? And Where does this reactant come from?

Pyruvate, Which is the product of Glycolysis in the cytoplasm

What are The Products of the Stage 2 Acetyl- CoA reaction for every 2 Pyruvate?

2 Acetyl CoA

2 NADH

2 CO2

what do you need to know about the krebs citric acid cycle
What do you need to know about the Krebs Citric Acid Cycle?

What are the products of the Krebs Cycle for every 2 Acetyl CoA molecules?

2 FADH2 2 ATP

6 NADH 4 CO2

Starting with one glucose in the beginning of Glycolysis, How many spins of the Krebs Cycle will occur?

2 Spins

electron transport chain and chemiosmosis review
Electron Transport Chain and Chemiosmosis review.

How are the FADH2 and NADH molecules made throughout aerobic respiration used in the ETC and Chemiosmosis?

They become reduced and give their H+ ions to create a proton gradient for chemiosmosis.

How does the proton gradient result in the creation of ATP molecules during Chemiosmosis?

The ATP synthase sends the H+ ions through the inner membrane and phospharlizes ADP into ATP

How is Water (H2O) created in the Electron Transport Chain?

The final electron acceptor is oxygen which takes the electron and becomes H2O

how much nadh is created in each of the stages
How Much NADH is created in each of the stages?

Glycolysis

Oxidation of Pyruvate

Krebs Cycle

2 NADH

2 NADH

6 NADH

how are atps made at each stage
How are ATPs made at each stage?
  • Glycolysis- net 2 (substrate level phosphorylation)
  • Stage 3 – Krebs cycle- 2 ATP made (substrate level phosphorylation)
  • ETC and chemiosmosis –oxidative phosphorylation -32 more!
  • Net = 36 ATP
