Cellular Respiration Cellular Respiration: metabolic
reactions that convert stored chemical energy into usable chemical energy (ATP).
Where? inside cells of organisms
Two Major Types Aerobic Respiration- oxygen (electron
acceptor) is required to generate ATP Anaerobic Respiration- talk about this later.

Stage 1 of Cellular Respiration
Most Common Example: Glycolysis
Glycolysis: breaking down of glucose
Glucose pyruvate + ATP
Pyruvate = 3 Carbon sugar

Steps of Glycolysis 1. Phosphates from two ATP molecules are
transferred to a single glucose molecule to make a 6- C- PP compound (takes three reactions)
2. The 6-C-PP compound is broken down into two 3- C- P compounds (takes two reactions)
3. Another phosphate is is added to the two 3- C- P compounds to make two 3- C- PP compounds
4. Each 3- C- PP compound is converted into pyruvate, producing four 3-C pyruvates (takes four reactions)

Aerobic Respiration Summary
Goal: To make lots of ATP = usable chemical energy for the cell
Krebs Cycle
Uses pyruvate to free electrons
Electron Carriers: NADH, FADH2
Electron Transport Chain
Electrons used to create a H+ gradient to leave via ATP synthase to make ATP.

Pre- Krebs Cycle Pyruvate enters a mitochondrion and is
converted into a 2-C compound
By product is a 2-C acetyl molecule (different 2-C compound)
Acetyl binds to a molecule called coenzyme A (CoA) to make acetyl-CoA.

Krebs Cycle1. Acetyl-CoA binds to a 4-C compound, to make a
6-C compound and releases coenzyme A
2. CO2 is released from 6-C compound, to make a 5-C compound. Electrons are transferred to NAD+, to make NADH
3. CO2 is released from the 5-C compound, to make a 4-C compound. ATP is made and NADH are made
4. 4-C compound is converted into a different 4-C compound. Electrons are transferred to FAD, to make FADH2
5. New 4-C compound is converted to original 4-C compound to continue cycle. NADH is made.

Electron Transport Chain1. Electrons from electron carriers NADH and
FADH2 pass through the ETC located in the inner mitochondria membrane
2. Energy from the electrons is used to pump H+ ions outside the inner mitochondria compartment
3. Since there is a higher concentration of H+ ions outside, they are transported back inside through carrier protein ATP Synthase
4. ATP Synthase uses the H+ ion gradient to combine ADP & P to make ATP
5. The used electrons and H+ ions bind with oxygen to form water.
