Document Summary

Bms 1004 intro to cell and molecular biology recitation. Where does krebs cycle occur?-mitochondria-matrix (none of the above) Steps of glycolysis-glucose turns into glucose 6-p with hexokinase, turns into fructose 1-6 biphosphate with isomerase, turns into fructose-1 and 1-6 bis-phosphate with 2 atp. After creation of fructose 1-6 bis-phosphate-point of no return/commitment step. Anaerobic respiration in eukaryotes-lactic acid+2atp while prokaryotes-ethanol and co2. Golgi apparatus-package, transport, processing, sorting, not protein synthesis. Distilled water goes into cell-cell bursts, distilled water is hypotonic. Which of the following occurs in the cytoplasm-glycolysis only. Breakdown of co2 to h2o involves glycolysis, breakdown of pyruvate into acetyl group, citric acid cycle.
