UL Lafayette Krayesky Biology 110 Exam 2 Questions With
Complete Solutions
...They are controlled by competitive and non competitive
inhibitors Correct Answers HOW is an enzyme controlled
made active or inactive
1. The photon could go through the atom and not hit any
electrons
2. The photon could hit the nucleus and reflect off it. It would
change its wave length after reflection.
3. The photon could hit an electron and the electron would
become excited and rise to a higher energy shell. Correct
Answers What happens to electrons when they are hit by light?
(three possibilities)
2. One off of Ketoglutarate at step 4. and Succinyl-COA at step
5 Correct Answers How many carbon dioxide molecules are
created during CAC. where did they come from?
3 Correct Answers How many NADH do you get from the
citric acid cycle per pyruvate
3 phosphaglycerate Correct Answers What is 3PG
30 for NADH, 4 for FADH2 Correct Answers How many ATP
are formed as a result of electrons carried by NADH? what
about FADH2
36 Correct Answers How many ATP do you get in a
eukaryotic cell when oxygen is present?
,36 ATP Correct Answers If you break one glucose and oxygen
is present, you will get ________
4 ATP are formed=Gross
but only 2 ATP are net Correct Answers 4 ATP are
formed=Gross
but only 2 ATP are netHow many ATP are formed during
glycolysis
6 Correct Answers How many NADH do you get in the CAC
per glucose
a high concentration of hydrogen outside the mitochondrial
matrix Correct Answers a high concentration of hydrogen
outside the mitochondrial matrixWhat is the proton motive
force? and where is it found
A protein that acts as a catalyst to speed up a chemical reaction.
Correct Answers What is an enzyme and what does it do?
Acetyl CoA Correct Answers What molecule cycles in CAC
Activation energy Correct Answers 1. The initial input of
energy to start a reaction
2. Allows molecules to get close enough to cause bond
rearrangement
Active site Correct Answers Location where reaction takes
place
, Active site Correct Answers the site in the enzyme where
chemical reactions take place
Active transport Correct Answers The movement of a
substance from an area of low concentration to high
concentration with the aid of a transport protein and a source of
energy.
Allosteric site Correct Answers Binding causes
conformational change in enzyme inhibiting enzyme function.
outside the active site
Amphipathic Correct Answers Both hydrophobic and
hydrophilic.
Anabolic Correct Answers Linking molecules together,
producing stored energy
Antiporters Correct Answers Two solutes move in opposite
directions.
ATP Correct Answers Adenosine Triphosphate, most common
energy source for cells
ATP Synthase Correct Answers What molecular machine
forms ATP?
Because the splitting of water gives an electron to PSII for it to
run. Correct Answers Why is water required for the non-cyclic
light reactions
