BIOL 2P03 Lecture Notes - Lecture 8: Inner Mitochondrial Membrane, Thylakoid, Mitochondrial Matrix
Document Summary
Inner chloroplast membrane: thylakoid membrane, pigments found in here absorb the light, photosynthesis only occurs in animal cells, where does the calvin cycle take place, mitochondrial matrix. Inner mitochondrial membrane: chloroplast stroma, thylakoid membrane, cytosol. Anaerobic metabolism: much faster but not as efficient as aerobic metabolism, wastes energy on glucose molecules. Aerobic metabolism: produces more energy, with oxygen, pyruvate goes into mitochondria and produces acetyl-coa. Pathways: glycolysis: glucose is converted into 2 pyruvates (oxidations) atp via substrate level phosphorylation (moving phosphate from high molecule to generate atp) electrons transferred from nad to create nadh etc . Glycolysis occurs in the cytosol of the cell. Glucose 2 pyruvate that generates atp and nadh: pyruvate with oxygen goes into mitochondria, pyruvate without oxygen we generate lactate (donating electrons to pyruvate that generates lactate) Lactate is acidic cramps during exercise (not enough oxygen going to cells, generates a lot of lactate)
