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

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
![Page 13: Cellular respiration](https://reader035.vdocuments.site/reader035/viewer/2022062703/55503accb4c9058f768b45d9/html5/thumbnails/13.jpg)
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
