Cell respiration

Cell Respiration-an aerobic process of releasing energy from sugars to make ATP.

C6H12O6 + 6O2

6CO2 + 6H20 + Energy


Cell respiration

ATP Synthetase

ATP-ase


Cell respiration

ATP- a molecule that temporarily stores chemical energy and transfers it to cell processes (and bodily movement at large.)

Adenosine Triphosphate

Stages:

Glycolysis

Kreb’s Cycle

Electron Transport Chain


Cell respiration

Cell Respiration

Stages:

Glycolysis is the process of breaking down glucose into two pyruvic acids (3-carbon compound) through hydrolysis. During this process 2 ATPs are used up.

Cell Respiration

ADPs re-enters the process and takes the energy that binds the phosphates to the 3 C molecule as well as the phosphates to remake ATPs.

Cell respiration

Glycolysis

Cell Respiration

Glycolysis requires no oxygen for it to occur (anaerobic).

This hydrolysis of glucose takes place in the cytoplasm of the cell.

Stages:

Citric Acid Cycle is an aerobic series of chemical reactions occurring within the cell, responsible for the final breakdown of food molecules to form carbon dioxide, water, and energy.

Cell Respiration

Stages:

Electron Transport Chain refers to a series of oxidation processes where electrons carried by NADH and FADH2 are transferred to electron acceptors. This occurs along the inner membrane of each mitochondrion.

Cell respiration

Electron Transport Chain

Cell Respiration

Along the inner membrane of mitochondria are embedded proteins. As with electron transport chain in photosynthesis, proteins make up the electron transport chain in cellular respiration.

Cell respiration

Electron Transport Chain

Cell Respiration

Electrons from NADH and FADH2 are transferred to the proteins embedded in the inner membrane.

These electrons will be transferred from one protein to another and eventually pumping in the hydrogen from the intermembrane space to the inside of the inner membrane.


Cell respiration

Electron Transport Chain

Cell Respiration

This is a carrier protein that once energized by some electrons from NADH and FADH2 will make an action that allows hydrogen to move into the matrix (inside the inner membrane)


Cell respiration

Electron Transport Chain

Cell Respiration

Matrix (inside the inner membrane)

Hydrogen ions will build up on the inside of the mitochondrial membrane. These high concentration of hydrogen will cause some of it to find a way out—through the ATP synthase

Inter-membrane space

Cell Respiration

Oxygen picks up electrons and hydrogen ions to form water. These water molecules are given off as waste products.
