Cell+Respiration

Processes in the Mitochondria: Glucose --> **1. Glycolysis occurs in the cytoplasm** Pyruvate/ Pyruvic acid --> acEtyl CoA -- > **2. Krebs Cycle occurs in the matrix**
 * 3. Oxidative Phophorylation** (ETC - Electron transfer chain) **occurs in the inner membrane**

Glycolysis - Glucose (6C) is broken into two molecules of pyruvate (3C) - 2 ATP and 2 NADH + 2H+ are generated from this state - No oxygen is required (the process is anaerobic) - Occurs in the cytosol/ cytoplasm of the cell NADH FADH 2ATP 2NAH

Krebs cycle/ Citric Acid cycle - The acetyl group passes into a cyclic reaction and combines with a 4 carbon molecule to form a 6 carbon molecule - The CoA is released for reuse - Successive steps in the cycle remove carbon as carbon dioxide - Occurs in the matrix of mitochondria 2 x (1ATP, 3 NADH, 1FADH)

Electron transport chain - Oxygen goes in, water comes out

Extra: Muscles have myoglobin, contains oxygen (makes them red)

Respiration - requires energy and generates heat (exercise --> sweat (feel hot)) Physical processes (see, hear, rapid contraction and relaxation of muscle require a lot of energy, as compared to when a person is writing)

Homework: 1. Read the rest of "cellular respiration 1" :D
