| what is cellular respiration? | complex process in which cells make (ATP) by breaking down organic compounds |
| what is glycolysis without oxygen? | fermentation or anaerobic respiration |
| what is glycolysis with oxygen? | aerobic respiration |
| where do glycolysis reactions take place? | the cytosol |
| what is fermentation? | in the absence of oxygen that pyruvic acid convert into other compounds that occur in the cytosol is known as fermentation |
| what is lactic acid fermentation? | an enzyme converts pyruvic acid into another three carbon compound called lactic acid |
| where does lactic acid occur? | 1.) occurs by microorganisms to manufacture food products, such as yogurt and cheese
2.) muscle cells in very strong exercise |
| what is alcoholic fermentation? | converts pyruvic acid into ethyl alcohol |
| how many ATP molecules are produced during glycolysis and anaerobic respiration? | two ATP molecules |
| what are the two major stages of aerobic respiration? | the kerbs cycle and the electron transport chain |
| where does the reactions of kerb cycle and electron transport chain take place in prokaryotes? | in the cytosol |
| where does the reactions of kerb cycle and electron transport chain take place in eukaryotes? | in the mitochondrial matrix |
| what is the kerbs cycle? | the kerbs cycle is a biochemical pathway that breaks down acetyl CoA, producing Co2, hydrogen atoms and ATP |
| what is the role of oxygen in aerobic respiration? | 1- Serves as a final electron acceptor.
2- Oxygen allows additional electrons to pass long chain .
3-oxygen accepts the protons
4-oxygen combines with proton and electron to form water |
| how many ATP molecules are made in cellular respiration? | 38 ATP molecules per molecule of glucose |
| what is more efficient glycolysis or cellular respiration? | cellular respiration |
| why does the equation of aerobic respiration can be considered the opposite of the overall equation of photosynthesis? | Because the products of photosynthesis are reactants in Aerobic respiration and the products of Aerobic respiration are reactants in photosynthesis. |
| what is the function of aerobic respiration? | 1. provides the ATP for all cells need to support the activities of life.
2-build the macromolecules that cells need. |
