General ideas about cell respiration:
1. What organisms perform cell respiration?
All organisms, autrophs and heterotrophs. 2. What is the purpose of cell respiration? Produce ATP
Using the energy
stored in the
bonds of
food molecules:
l. Carbs
2. lipids
3 proteins
3. Are there different kinds of cell respiration? What makes them different?
Aerobic Respiration uses Oxygen and is completed in the mitochondrion. Anaerobic Respiration no oxygen is needed it happens in the cytoplasm.
4. Write the equation that represents oxidative Cell respiration
5. Where does the energy to start the reaction comes from?
From 2 molecules of ATP
Nov 24­7:57 AM
Oxidative cell respiration occurs on 3 steps:
1
2
3
1. Glycolysis: Takes place in the cytoplasm. Glucose is converted into pyruvic acid with a net gain of 2 ATP.
2. Krebs Cycle or citric acid cycle: Occurs in the inner part of the mitochondria. Pyruvic acid first react with acetyl coenzyme and produces citric acid. As citric acid is broken down into CO2, NADH, ATP FADH2 are produced
and 3. The electron transport chain uses the high energy electrons produced in the previous steps to produce 34 ATP. The low energy electrons are finally bound to Oxygen to produce water.
