Cellular Respiration Cellular respiration is the process in

which plants and animals convert FOOD into ENERGY (ATP!) in their cells. This occurs in the Mitochondria!

Energy is stored in the form of ATP!!

ADP – after ATP is broken down

Two types of respiration:

(1) Aerobic (uses O2) - Glucose is broken down to CO2 and water with the help of enzymes to produce ENERGY!!

3 stages of aerobic respiration Glycolysis

Citric Acid Cycle

Electron Transport Chain

(2) Anaerobic (doesn’t use O2) Glycolysis and Fermentation

It all starts with Glycolysis:

Where:

In cytoplasm of cells

Requires 2 ATP to

initiate & produces

4 ATP at the end

=net gain of 2 ATP

What:

Uses glucose from

ingestion or PS

& breaks it down

into pyruvate

This pyruvate can

be used in 2

ways…

Pyruvate moves into the mitochondria and is converted to acetyl-CoA

1st way: Aerobic RespirationOccurs in ALL eukaryotic organisms!

Occurs in the mitochondria of cells!

C6H12O6 + 6O2 6H2O + 6CO2 + 36 ATP

Why is the

Mitochondria

a good

structure

for Cellular

Respiration?

B/c high surface

area on highly

folded inner

membrane

allows for more

rxns to occur!

LEADS TO MORE

ATP!!!

Aerobic Respiration includes Citric Acid Cycle/Kreb’s Cycle: pyruvate is

modified and carbons from it bond to oxygen to

form carbon dioxide, which is released!

2 ATP made!

Electron Transport Chain: e- are transported,

energy is released & form 32 ATPs!

At the end of the chain, the extra Hs bond to

oxygen to form water!

Foldable Part 2 – Information about

Aerobic Respiration (Glycolysis, Krebs

Cycle, ETC)

Foldable will include who does it, what

is the process, where does it occur,

when does it occur, how does it occur

(i.e. organelle, different processes in

different parts of each organelle,

reactions, etc)

Aerobic Vs. Anaerobic Respiration

Aerobic Respiration – requires O2

Anaerobic Respiration – Does not require O2.

– Also called Fermentation – occurs in yeast, bacteria, and muscle cells of animals.

– This occurs in the cytoplasm of the cell!!

Think about bacteria…how are they different from all other organisms?

2 types of Fermentation Lactic Acid Fermentation

– Occurs in the muscle cells of animals

– Glucose Lactic acid + 2 ATP

– Sore muscles after exercise!

Alcoholic Fermentation

– Occurs in yeast

– Glucose Alcohol + CO2 + 2 ATP

– Used in alcohol production!

What is this???
