What happens when a suitable substrate binds to an enzyme? - ANSWER: The
active site amino acids bond with the substrate
Cyanide binds to cytochrome oxidase at a site where the substrate oxygen would
normally bind. This is an example of - ANSWER: competitive inhibition
an example of a catabolic reaction is - ANSWER: lactate fermentation
what is an anabolic process that is endergonic and endothermic? - ANSWER: CH₄
+2O₂ → CO₂ + 2H₂O
ATP yields 7.3 kcal/mol of free energy and it is coupled with many enzyme
reactions that would not otherwise happen. Which can be coupled with ATP
hydrolysis to become a spontaneous reaction? A reaction with a G value of
_______? - ANSWER: 5
which process occurs under both aerobic and anaerobic conditions - ANSWER:
glycolysis
what is the key regulatory enzyme in glycolysis inhibited by the accumulation of
first committed product of the Krebs cycle? - ANSWER: phosphofructokinase
,2|Pag e
in this reaction NADH + Pyruvate → NAD⁺ + Lactate, Pyruvate becoming lactate,
is a/an _______________ process and _______________ is the OXIDIZING or
REDUCING agent. - ANSWER: reduction, NADH, REDUCING
the outputs of Krebs cycle that transfer energy to the electron transport system are -
ANSWER: FADH₂ and NADH
the output of glycolysis include ATP, ____________, and _____________ -
ANSWER: NADH and pyruvate
Which poison can inhibit the generation of delta [H⁺]? - ANSWER: A chemical
that would make the inner mitochondrial membrane leaky to ions
lack of oxygen during cellular respiration will inhibit Krebs Cycle and Acetyl CoA
formation inside mitochondria, even though oxygen is not an input in such
processes because under anaerobic conditions - ANSWER: Water is not formed
each FADH₂ produces less ATP when compared to NADj in oxidative
phosphorylation because ______________________ - ANSWER: FADH₂ gives
electrons at a lower energy level to the ETC and hence makes less ATP
What is not directly associated with photosystem II? - ANSWER: calvin cycle
th parts of plant tissue, namely ______________ & ______________ allow
transport of water and sugar respectively. - ANSWER: xylem and phloem
when the phosphorylation occurs during least reactions, the pH of the thylakoid
space will _______________ compared to the equilibrium state during night time -
ANSWER: decrease as the protons are pumped into the thylakoid
,3|Pag e
suppose a thylakoid is somehow punctured so that the interior of the thylakoid is
no longer separated from the stroma. This damage will have the most direct effect
on which process? - ANSWER: synthesis of ATP
when a suspension of algal cells is incubated in a flask in the presence of light and
CO₂ and then transferred to the dark, the release if oxygen stops. this reaction stops
when the algal suspension is placed in the dark because - ANSWER: the reaction
needs light
CAM plants can keep stomata closed in daytime, reducing water loss. This is
possible because they ______________
A)
fix CO2 into organic acids during the night by PEP carboxylase
B)
use photosystems I and II during day and night.
C)
use the enzyme phosphofructokinase, to fix CO2 more effectively
D)
fix CO2 into sugars in the bundle-sheath cells.
E)
fix CO2 into pyruvic acid in the mesophyll cells. - ANSWER: A)
fix CO2 into organic acids during the night by PEP
When RuBisCO enzyme was modified to reduce the binding of oxygen to
minimize photorespiration, the enzyme activity to fix CO₂ to carbohydrate was also
decreased. What is the possible reason for this result? - ANSWER: modified
enzyme lost to the binding to both O₂ and CO₂
, 4|Pag e
why is it important to reduce the chromosome numbers to half the original each
time for sexual reproduction of animals? - ANSWER: when the sperm and egg
cells they double the chromosome number and so we need to half the chromosome
number in the gametes
The homologous chromosomes separate during ____________________ and their
sister chromatids separate during _____________ phase of meiosis. - ANSWER:
anaphase I & anaphase II
the phases of meiosis that cause the most variation in the four daughter cells are -
ANSWER: prophase I & metaphase I
chromosome number is reduced to half the original number during meiosis because
- ANSWER: half of the chromosomes from each gamete are lost during
fertilization
what does not occur during mitosis? - ANSWER: crossing over between
homologous chromosomes
label the following examples as "exergonic or endergonic" and "exothermic or
endothermic" based on the changes in free energy and enthalpy respectively in
each of them
A. Simple Diffusion
B. Protein synthesis
C. Burning Fossil Fuels
D. ATP hydrolysis
E. Starch synthesis - ANSWER: A. exergonic & exothermic
B. endergonic & endothermic
