Cellular respiration

ATP Production

Aerobic Respiration

ATPAdenosine Triphosphate Structure

Base, sugar, 3 phosphates

Phosphate bonds Between two

phosphates Contains energy Energy released when

bond broken Energy stored when

bond created ATP is recyclable

Using ATP Cells use to build

molecules and organelles

Active transport Movement (muscles) Heat Bioluminescence

Respiration Purpose – to produce ATP energy Formula

C6 H12 O6 + 6O2--> 6H2 O + 6CO2 + ATP energy

TypesAerobicAnaerobic (Fermentation)

Cellular Respiration Vs. Systemic respiration

Stages of Aerobic Respiration

Glycolysis Occurs in Cytoplasm Energy

Uses 2 ATP to get started Produces 4 ATP (net gain?)

Reactant glucose

Products 2 pyruvic acids (pyruvate) 2 NADH

Electron carrier Carries to ETC

2 ATP (net gain)

Glucose

To the electron transport chain

2 Pyruvic acid

Glycolysis

Kreb’s Cycle (Citric Acid Cycle)

Occurs in matrix of mitochondria Energy

Produces 2 ATP Reactant

pyruvate Products

8 NADHCO2

What happens to this?

Oxidative Phosphorylation (Electron Transport Chain) Occurs on inner membrane of the mitochondria Reactant

NADH Oxygen

Product H2O

32 ATP

Net Gain of Aerobic Respiration 36 ATP CO2 and H2O are waste products

ATP Production

Anaerobic Respiration: Fermentation

Anaerobic Respiration

Glycolysis + Fermentation Purpose

Recycle NAD+

No more ATP

made

Types of Fermentation Lactic Acid Fermentation

Converts pyruvate into lactic acidUsed by humansUsed to make yogurt,

cheese, chocolate,

etc..

Types of Fermentation Alcoholic Fermentation

Converts pyruvate into ethanol and CO2

Causes dough to rise
