I Dream of Aerobic Respiration
Posted by admin under: Aerobics .
Our final lab video was a presentation of aerobic respiration, Lab number 9. Aerobic respiration is a process that produces large amounts of ATP in the mitochondrion in the presence of oxygen. The process starts off with pyruvate entering the inner matrix, which is called krebs cyle. During the cycle, pyruvate circles around in the inner matrix and releases ATP and CO2. The pyruvate is changed by a series of reactions to highly reduced electrons called NADH and FADH2. The NADH and FADH2 donate their electrons to the nearby cytochrome. The cytochromes form a chain-like structure on the inner membrane and pass these newly gained electrons down the chain. Making the cytochrome excited and thus pumping protons from the inner matrix into the intermembrane space, through active transport. Chemiosmotic gradient is formed next, this begins when the intermembrane is pH 5 and the inner matrix is pH 7. The ATP synthase becomes activated and forms a channel which allows the built up the protons to pass through the channel, through passive transport, moving back into the inter matrix. When the protons exit the ATP synthase they move with a great deal of energy which phosphorylates ADP and P into ATP.

Man, I never expected that searching YouTube for “ATP Synthase” would turn up anything, let alone this. Rock on. XD

i thought acetyl coenzyme A entered the kreb cycle…after pyruvates converted to it in the link reaction
