Respiration Quiz
Stuff from Respiration hws
| Question | Answer |
|---|---|
| What is the chemical formula for cellular respiration? | C6H12O6 + 6O2 ---> 6CO2 + 6H2O + 36 ATP |
| what is the function of cellular respiration? | change high energy electrons of food into lower energy ATP's |
| define high energy electron | electron found in bond between hydrogen and carbon atom, far away from the nucleus. High energy |
| Where are these electrons found? | far from nucleus in bond between hydrogen and carbon atom |
| anaerobic reaction | don't use oxygen to release energy from glucose |
| aerobic reaction | use oxygen to release energy from glucose |
| which produce more energy? | aerobic |
| What does glycolisis use? | anaerobic |
| where does glycoslis occur? | cytoplasm |
| what are the types of energy molecules created in glycoloisis? | ATP and coenzymes |
| how many coenzymes and atp are created in glycolosis | 2 |
| what needs to be available in the cell for pyruvate to enter the mitochondria? | oxygen |
| what does aerobic respiration convert pyruvate into? | carbon dioxide, water, energy (coenzyme NADH and FADH2) and 34-36 ATP |
| what are the two main purposes of the Krebs Cycle? | get rid of carbon dioxide, and make coenzymes |
| what is the reactant that enters glycolosis | glucose |
| what energy is added to start glycolosis | 2 atp |
| what are the energy products of glycolosis | 4 atp 2 coenzymes |
| where does the krebs cycle occur | mitochondria |
| what reactant enters krebs cycle | pyruvate |
| what is the low energy product of krebs cycle | CO2 |
| what is the high energy products of krebs cycle | coenzymes, atp |
| glycolosis splits glucose in half into two... | pyruvate |
| glycolisis occurs in the________ no _____________ is used this is ______________ process | cytoplasm, oxygen, anaerobic |
| how many net atp does glycolisis produce? | 2 |
| coenzymes temporarilly carry________________________ that will be changed into___________ the cell can use | high energy electrons, ATP |
| what kind of respiration occurs when the two pyruvates enter the mitochondria? | aerobic |
| what kind of process is the krebs cycle | aerobic |
| glycolisis produces ___________ pyruvates so the Pre krebs and krebs cycle will occur________ | two, twice |
| how does carbon leave the krebs cycle and mitochondria? | combines with oxygen, diffuses into bloodstream, diffuses into lungs, diffuses into air. (breathed out) |
| what is the last step of cellular respiration? | electron transport chain |
| what proteins are the membranes inside the mitochondria embedded with? | proton pumps |
| how to proton pumps work? | proton pumps use high energy electrons to pump protons through the membrane from low to high concentration |
| what kind of transport is the electron transport chain? | active |
| _______________ NAD and FAHD2 drop off _____________________________ at the first of three _______________ | coenzymes, high energy electrons, proton pumps |
| as the high energy electron pass through the proton pump it....... | pumps protons across a membrane from low to high concentration |
| what is the membrane protein that the protons squeeze through called? | ATP synthase |
| what does ATP synthase do? | uses the force of a proton passing through the membrane to attach a phosphate to ADP making it ATP |
| as the elctron goes through the proton pump it___________ energy | loses |
| (after ETC) this low energy electron attaches to ____________ which picks up 2________________ and is converted into water | oxygen, free floating hydrogen protons |
