BIOL 133 - Exam 2 Study Guide
Questions And All Actual Answers.
Fe3+ - Answer What is not a good biological oxidizing agent?
Riboflavin - Answer What vitamin derivative accepts hydrogen for complex I during ETC?
Deamination - Answer Removal of NH3 is best described as ____________ .
4 - Answer Assuming 2 ATPs are produced per FADH2, how many ATPs will be produced in oxidative
phosphorylation per glucose molecule?
when α-Ketoglutarate is oxidized to Succinyl CoA - Answer When has glucose been broken down from
its original 6 carbon molecule to 6 molecules of carbon dioxide?
* ATP is not energy dense enough.
* ATP is not stable enough. - Answer In gluconeogenesis, organisms use ATP to make glucose, then in
cellular respiration they break down the glucose again to get energy. Why not just store the ATP? (Select
all that apply.)
pyruvate oxidation - Answer Molecules generated from butter will enter aerobic cellular respiration at
oxidation/reduction reactions - Answer NADH and FADH2 are products of
6 - Answer ____________ carbon dioxide molecules are given off during three turns of the Krebs cycle?
complex II - Answer What area is not involved with pumping protons to the intermembrane space?
Calvin cycle - Answer Organic molecules are made in the _______________ .
, both generate ATP by proton gradient - Answer What statement shows the relationship among
chloroplasts and mitochondria?
ability to fix carbon - Answer If rubisco does not function properly, what process would be affected?
3 - Answer ____________ membranes can be found in a chloroplasts.
convert CO2 into glucose - Answer The light independent reactions are important because they
sun→grass→cow→human - Answer What is the flow of energy in order from source to end?
quinone - Answer P700 first transfers an electron through chlorophyll and a bound
thylakoid lumen - Answer Protons from electron transport will amass in the
* Visible light's wavelengths are between 400-740nm
* Chlorophyll b absorbs a lot of energy from 460nm wavelengths
* Red absorbs little energy - Answer What properties are expressed by wavelengths? Select all that
apply.
oxidation and reduction - Answer Light-dependent reactions build NADPH and oxygen by
________________ .
protein activation - Answer Protein phosphorylating enzymes help regulated gene expression by
A cascade amplifies output from the original signal. - Answer A common theme in many pathways is a
cascade of similar enzymes acting on each other in sequence. For instance, MAP kinase kinase kinase
adds a phosphate to MAP kinase kinase, which adds phosphate to MAP kinase, which adds phosphate to
another substrate.
What is the benefit of using a cascade of enzymes?
