Bio Unit 2 Sec 1 #4
Bio Unit 2: Lecture 11: Energy Transfer
| Question | Answer |
|---|---|
| 2 ways energy is transferred in living systems is ________ and ______ ______ | Phosphorylation; Redox Reactions-Oxidation |
| Phosphorylation provides ______ energy to the system | Usable |
| In phosphorylation, the ____ donates a phosphate to a system and this provides energy to the system | ATP |
| ATP has ____ phosphates and has _____ energy | 3; Potential |
| ADP has ____ phosphates | 2 |
| When ATP is converted to ADP, the third phosphate(Pi) is _____ to the system to provide ______ | Donated; Energy |
| The conversation of ____ TO _____ gives off energy | ATP; ADP |
| The conversation of ____ TO _____ requires energy | ADP; ATP |
| When ADP converts TO ATP, the phosphate is _____ to the ATP molecule and energy is put into the process | Added |
| In _____ level phosphorylation, the compounds in cells donate a phosphate to quickly _____ ADP to ATP | Convert |
| An example of Substrate Level Phosphorylation is ______ Phosphate | Creatine |
| Redox Reactions-Oxidation/Reduction Reactions involve the movement (adding or removing) of a ______ atom from one compound to another | Hydrogen |
| Removing a hydrogen compound (H+) is called _____ | Oxidation |
| Adding a hydrogen compound (H+) to a compound is called _____ | Reduction |
| The movement of H+ equates to energy transfer b/c the H+ has an associated _____ that has ENERGY, so when the H+ is moved, it's _______ containing electron goes with it | Electron; Energy |
| Electrons = ______ | Energy |
| Glucose has potential energy because it is highly________ (has lots of hydrogen) so it has the potential to give its _______ and associated electrons to another compound, therefore providing energy | Reduced; Hydrogen |
| _______ shuttle energy in cells through redox reactions | Coenzymes |
| Coenzymes found in cellular respiration are _____ to NADH and FAD to _____ | NAD; FADH2 |
| Coenzymes found in photosynthesis are NADP to ______ | NADPH |
| Coenzymes pick up ______ and associated electrons and carry them to another system where _______ is needed | Hydrogen; Energy |
| NADH, FADH2, and NADPH have a lot of _____ energy because they are shuttling energy containing _________ and associated electrons | Potential; Hydrogen |
