Aerobic Respiration

Aerobic Respiration has

O₂

Aerobic Respiration

C6H 12O 6 + 6 O 2 ——> 6 CO 2 + 6 H 2O + Energy

Glycolysis Overview

sugar breakdown

GLUCOSE is the primary source

occurs in 2 phases

Where does Glycolysis happen

the cytoplasm of all organisms

Phase Levels 1-5 of Glycolysis

Energy Investment Phase

Phase Levels 6-10 of Glycolysis

energy yielding phase

Glycolysis 1.) Glucose

Pyruvate

Pyruvate is regulated by

Acetyl CoA, NADH, NAD

Glycolysis 2.) ADP + Pi

ATP

Glycolysis 3.) NAD

NADH

First committed Step: # 1 of Glycolysis

Glucose + ATP —→ Glucose - phosphate + ADP.

First committed Step: # 1 of Glycolysis is Catalyzed by

Hexokinese

3rd Key Step of Glycolysis

Fructose - Phosphate +ATP —→ Fructose – bisphosphate + ADP

3rs Step of Glycolysis is Catalyzed by

Phosphofructokinase (PFK)

Acetyl CoA happens

BEFORE krebs

Acetyl CoA from carbs

fats sttorage to avoid excess GLUCOSE in blood

Acetyl CoA from fats

derived from lipids through BETA OXIDATION, help make lipids

Where does Acetyl Coa happen in eukaryotic cells

mitochondria

Where does Acetyl Coa happen in prokaryotic cells

cytoplasm

Where does the Krebs Cycle Happen

matrix

Key Step #1 of Krebs Cycle

First Committed Step: Acetyl CoA + Oxaloacetate —> Citrate

What is the Key Step #1 of Krebs Cycle Catalyzed by

Citrate Synthase

Citrate Synthase is regulated by

high levels of ATP

Key Step 3 of Krebs Cycle

Rate Limiting Step: Isocitrate +NAD + —> a-ketoglutarate +NADH + CO2

What is the Key Step #3 of Krebs Cycle Catalyzed by

Isocitrate Dehydrogenese

Isocitrate Dehydrogenese is regulated by

high levels of ATP NADH

Krebs Cycle 1.) Acetyl CoA

CO₂ + CoA

Krebs Cycle 2.) NAD

NADH + H

Krebs Cycle 3.) FAD

FADH

Krebs Cycle 4.) ADP + Pi

ATP

Oxidative Phosphorylation 1.) NADH

NAD

Oxidative Phosphorylation 2.) FADH

FAD

Oxidative Phosphorylation 3.) ADP + Pi

ATP

Oxidative Phosphorylation 4.) O₂ + Electrons + H
