Process of cellular respiration
| Question | Answer |
|---|---|
| Glycolysis | Means sugar breaking;Chemical steps that transform glucose;During glycolysis 1 molecule of glucose,a 6 carbon compound, is transformed into 2 molecules of pyruvic acid,a 3 carbon compound. |
| NAD+ | Nictotinamide adenine dinucleotide;Accepts pair of high energy electrons;electron carrier |
| Krebs Cycle | Second stage of cellular respiration;Name after Hans Krebs British biochemist;During Krebs cycle pyruvic acid is broken down into carbon dioxide in a series of energy extracting reactions; Also known has the citric acid cycle |
| Matrix | Innermost compartment of michondrion and the site of Krebs cycle reactions. |
| What happens during the process of glycolysis? | During glycolysis 1 molecule of glucose,a 6 carbon compound, is transformed into 2 molecules of pyruvic acid,a 3 carbon compound. |
| What happens during the Krebs cycle? | Pyruvic acid is broken down into carbon dioxide in a series of energy-extracting reactions. |
| How does the electron transport chain use high energy electrons from glycolysis and krebs cycle? | The electron transport chain uses the high energy electrons from glycolysis and Krebs cycle to convert ADP and ATP |
| How much ATP does cellular respiration generate? | release about 36 molecules of ATP per molecule of glucose. |
