Energy or “currency” used by all your Cells.Adenosine Triphosphate

Organic molecule (contains carbon) with three high-energy Phosphate bonds

ENERGY!ENERGY!

3 Phosphates Ribose Sugar

Adenine Base

Through a process called cellular respiration

6CO2 + 6H20 + e - + 36-38ATP’s

C6H12O6 + 6O2

YIELDS

Glycolysis

The Citric Acid Cycle (Krebs Cycle)

The Electron Transport Chain

It takes place in two different parts of the cell:Glycolysis occurs in the CytoplasmKrebs Cycle & ETC Take place in the Mitochondria

Occurs in Cytoplasm

Occurs in Matrix

Occurs across Cristae

• Also produces 2 NADH and 4 ATP

• Pyruvate is oxidized to Acetyl CoA and CO 2 is removed

ATP

NETS: 3NADH

1ATP

1FADH2

2CO2

Each turn of the Krebs Cycle also produces 3NADH, 1FADH2, and 2CO2

Therefore, For each Glucose molecule, the Krebs Cycle produces 6NADH, 2FADH2, 4CO2, and 2ATP

NAD + (nicotinadenine dinucleotide) acts as the energy carrier

NAD + is a coenzyme

It ’s Reduced to NADH when it picks up two electrons and one hydrogen ion

34 ATP Produced H 2O Produced Occurs Across Inner Mitochondrial

membrane Uses coenzymes NAD+ and FAD+ to

accept e- from glucose NADH = 3 ATP’s FADH 2 = 2 ATP’s

1. What are three parts of cellular respiration?

2. Where does cellular respiration occur?

3. What are the “inputs” and “outputs” for each of the three stages?

So far, everything we’ve talked about has required oxygen. What happens if oxygen isn’t present? ◦ What are some situations that would lack oxygen?

Lactic acid fermentation is a biological process by which glucose is converted into energy and the metabolite lactate. It is an anaerobic fermentation reaction that occurs in some bacteria and animal cells such as muscle cells.
