mitochondria +aeorbic respiration

Structure of mitochondria

Outer membrane : simple and oremeable to many molecules

Inner membrane: more complex - organized into lots of folds called cristae (singular: crista)

In the inner membrane is a fluid called the matrix. It contains enzymes necessary for the Krebs cycle.

Cristae

Greatly increases the surface area of the inner membrane to allow a higher transport rate of reactants and products, therefore enhancing its ability to produce ATP (Energy)

folded membrane inside mitochondria where the electron transport chain occurs

Respiration

Process of converting biochemical energy from nutrients into usable energy(ATP)

Aerobic respiration word equation

Glucose + oxygen > carbon dioxide + water + ATP

Aerobic respiration chemical equation

C6H12O6 +602 > 6CO2 + 6H20 + ATP

Glycolysis

In: glucose

Out: 2 pyruvate and 2 ATP

Location Cytoplasm

occurs in cytoplasm of the cells and is broken down into pyruvate ;this stage does not require oxygen and produces 2 ATP molecules as well as hydrogen which move to the cristae

Krebs cycle

In: pyruvate > acetyl CoA

Out: 2ATP, CO2,H+

Location:Mitchoxhondrial matrix

pyruvate enters the matrix of the mitochondria; CO2 is removed, producing acetyl coenzyme A and more hydrogen which moves to the cristae. Producing CO2, hydrogen + and 2 ATP

Electron Transport Chain

In: H+

O2

Out: 34ATP + H20

Location: Cristae of mitochondria

Occurs on the cristae of the mitochondria. The hydrogens are passed along the electron transport chain, releasing energy which is captured as 34 ATP. Oxygen is required at this stage and water is produces. Each glucose molecule produces 36 ATP during aerobic respiration
