Respiration - Aerobic

What is Respiration (basic)

The process of making energy

Types of Respiration

Aerobic respiration which requires oxygen and
Anaerobic respiration which does not use oxygen

Where does respiration occur?

In the cytoplasm and mitochondria

What does Aerobic Respiration involve

It involves Glycolysis where glucose (5 C) is broken down to pyruvate (3 C)

Process of Glycolysis (Part 1)

Glucose undergoes phosphorylation and gains an inorganic phosphate from ATP —> ADP, forming Glucose Phosphate

Glucose Phosphate undergoes isomerism to form Fructose Phosphate

Process of Glycolysis (Part 2)

Fructose Phosphate undergoes phosphorylation and gains an inorganic phosphate from ATP —> ADP, forming Fructose 1,6 bisphosphate

Fructose Phosphate undergoes Lysis, splitting into Dihydroxyacetone and Glyceraldehyde3phosphate

Process of Glycolysis (Part 3)

Glyceraldehyde3phosphate undergoes oxidative phosphorylation, gaining 2 inorganic phosphates and converting 2NAD —> NADH2 to form 2 molecules of Glycerate 1,3 bisphosphate

In the process of phosphorylation, 2 molecules of Glycerate 1,3 bisphosphate each give away an inorganic phosphate to ADP, 2ADP —→2ATP, forming 2 molecules of 3Phsphoglycerate

Process of Glycolysis (Part 4 - Final)

In the process of phosphorylation, 2 molecules of Phosphoglycerate each give away an inorganic phosphate to ADP, 2ADP —→2ATP, forming 2 molecules of Pyruvate

Where does glycolysis occur

In the cytoplasm

What are the general investments and products made in glycolysis

Invest 2 ATP and produce 4 ATP in total (2 Net ATP made)

Components of the Mitochondria

Outer Membrane
Inner Membrane / Cristae
Circular DNA
Food Store
Matrix
Ribosome

Where does the electron transport chain occur

In the cristae of the mitochondria

What is the second part of Aerobic Respiration

The Link Reaction

What is the Link Reaction? How and When does it occur

It is the second part of Aerobic Respiration and it occurs only when oxygen is present. Pyruvate is actively transported into the matrix

Process of the link reaction

2 molecules of Pyruvate undergoes oxidative Decarboxylation where 2 NAD ——> 2NAH2 with the emission of 2 CO2 to form 2 molecules of Acetyl CoA

Summary of the Link Reaction

Pyruvate loses a C to form CO2 and H to form NADH2 and produces Acetyl which binds to CoA to enter the Kreb Cycle

Process of the Kreb Cycle

Oxaloacetate (4C) accepts an Acetyl (2C) to produce Citrate
