|
Write the overall chemical equation for cellular respiration? |
6O2+C6H12O6~38ATP +6CO2 +6H2O |
|
|
Identify the process that produces each product as either glycolysis, Kreb's cycle, or electron transport/chemiosmosis. From the chemical equation for cellular respiration? |
38ATP = Glycolysis, Kreb's cycle and Electron transport 6CO2 = Kreb's cycle 6H2O = Electron transport |
|
|
Identify the products of glycolysis. Identify where each of the products will be used in the other steps of cellular respiration? |
1. Pyruvic Acid-- Start of the Kreb's cycle 2. NADH-- electron transport chain 3. ATP-- can use in next round of glycolysis |
|
|
Write the overall chemical equation for the initiation of the Kreb's cycle involving the formation pf acetyl CoA? |
2 Pyruvic Acid~ 6CO2 + 8NADH + 2FADH2 + 2ATP Pyruvic acid is 1st decarboxylated to form Acetyl CoA |
|
|
Identify the major products produced by the Kreb's cycle? |
Products are NADH, FADH2 & ATP |
|
|
What is the major wast produce that is formed during Kreb's cycle chemistry? |
Waste product is CO2 |
|
|
Where do the electrons come from that are used in the electron transport chain? |
Electrons come from NADH & FADH2 made earlier |
|
|
How do electron transport chain proteins actively pump hydrogen ions against their concentration gradient during the electron transport chain? |
Electrons transport chains use proton pumps to pump protons across the membrane |
|
|
What are the built up hydrogen ions used for? |
A proton gradient is created, generating an electrochemical gradient with potential NGR= called a proton motive force |
|
|
What enzyme produces ATP during chemiosmosis? |
ATP synthase makes ATP from ADP and Pi |
|
|
How many ATP are produced during each of the three steps of cellular respiration? |
Glycolysis = 2ATP Kreb's= 2ATP Electron transport = 34 ATP |
|
|
How many pruvic acids does it require to produce the many ATP? |
2 Pyruvic acid to produce that many ATP |
|
|
What are two fuels other that glucose that can be used during cellular respiration? |
Lipids and Proteins |
|
|
What is the bi-products are produced when using Lipids as an alternative fuels exclusively? |
Lipids-- break down into glycerol & fatty acids both broken down to Acetyl CoA |
|
|
What is the bi-products are produced when using Proteins as an alternative fuels exclusively? |
Proteins== break down into substance that can enter Krebs cycle |
|
|
Which cell would produce more ATP a coccus bacteria using oxygen as its terminal electron acceptor or a yeast cell fermenting under anaerobic conditions? |
A cocus bacteria using O2 as a terminal electron acceptor would make more ATP |
|
|
Explain your answer with the correct ATP number per 1 molecule glucose. In coccus bacteria vs yeast cell fermenting? |
aerobic--38 ATP made/glucose anaerobic Ferment--2 ATP made/glucose |
|
|
What would be the results of inhibiting the electron transport chain proteins? |
If you inhibit e-transport proteins. There would be a build up of NADH & FADH2 and lower it would lower NAD+ and FAD+. |
|
|
What would be the results of inhibiting glycolysis and the Kreb's cycle? |
Glycolysis and Kreb's cycle would slow down (if not halt) without these chemical. |
|
|
Explain the difference between substrate phosphorylation and oxidative phosphorylation? |
Substrate-level--ATP generated when a high NRG phospate is directly transfer from a phosphoylate substrate to ADP. Oxidative-- E- are transfered from one e- carrier to another releasing NRG. Some of which is used to make ATP from ADP. |
|
|
Why is oxygen used as a terminal electron acceptor instead of Na+, Ca2+ or K+? |
Oxygen is used because its a strong oxidizer and will take up e- easily. When it takes up the electron from the e- carriers, it will pick up protons from NADH (which is a strong reductant). Plus Na+, Ca2+& K+ would reather lose electrons rather than gain them to become more stable. |
