HESI A2 STUDY GUIDE

Document Content and Description Below

 Mitochondria and chloroplasts- produce cellular energy; cellular respiration and photosynthesis  Cellular membrane- protect, communicate, and passage of substances into and out of the cell � ... �� Bilayer of phospholipids with proteins, cholesterol, and glycoproteins o Cellular respiration  ATP is energy currency of cell  NADH is the reducing agent and is a vehicle of stored energy; precursor to produce greater amounts of ATP in final steps of respiration o Glycolysis- conversion of glucose to pyruvate; cytosol of the cell and produces 2 molecules of ATP, two molecules of pyruvate, and 2 molecules of NADH o Citric acid cycle (krebs cycle)- pyruvate is transported to mitochondria, takes place in matrix of mitochondria, and for a single consumed glucose molecule, 2 ATP, 6 CO2 molecules, and and 6 NADH molecules are made. o Electron transport chain- begins with the oxidation of NADH molecules to produce O2 and finally H2O. For every glucose molecule, there are 32-36 ATP molecules produced. o [Show More]
