Grade A | 100% Correct
QUESTION
Cellular Metabolism
Answer:
Energy transformations that occur as chemicals are broken down or synthesized within the cell.
QUESTION
Catabolism
Answer:
breaking down
QUESTION
Anabolism
Answer:
synthesis
QUESTION
Hydrolysis
Answer:
a reaction that adds water to another compound. (2 hydrogens, 1 oxygen).
QUESTION
,Chlorophyll
Answer:
must be present for photosynthesis to occur, it is not used up in the process.
QUESTION
Chlorophyll has the ability to
Answer:
absorb a photon of light and is found in the grana of the chloroplast.
QUESTION
Electron Transfer System (ETS)
Answer:
produces the most ATP molecules, yielding 34 ATPs per glucose molecule.
QUESTION
The products of the Krebs cycle
Answer:
are easily converted to ATP, but the main energy products of the Krebs cycle liberate electrons
then used in the electron transfer reactions.
QUESTION
Photolysis is a reaction of photosynthesis where
Answer:
chlorophyll pigments absorb photons of light, leaving the chlorophyll in a higher energy
(excited) state, these then supply energy to reactions that produce ATP from ADP and Pi.
,QUESTION
Pi
Answer:
Inorganic phosphate
QUESTION
A mutation
Answer:
is an accidental change of the DNA sequence of the gene that can result in creating a change of
trait that is not found in the parent.
QUESTION
Differential reproduction
Answer:
proposes that those individuals within a population that are most adapted to the environment are
also the most likely individuals to produce viable offspring.
QUESTION
The Hardy-Weinberg Law of Equilibrium
Answer:
states that where random mating is occurring within a population that is in equilibrium with its
environment, the gene frequencies and genotype ratios will remain constant from generation to
generation. It is a mathematical formula that shows why recessive genes do not disappear over
time from a population.
QUESTION
Allopatric speciation
, Answer:
occurs when two populations are geographically isolated from each other. Over time this results
in the production of two separate species.
QUESTION
Gene Migration occurs when
Answer:
an individual from an adjacent population of the same species immigrates and breeds with a
member of a previously locally isolated group, resulting in a change in the gene pool.
QUESTION
The primary role of DNA in the cell
Answer:
is the control of protein synthesis. Genetic traits are expressed and specialization of cells occur as
a result of the combination of proteins produced by the DNA of a cell.
QUESTION
DNA replication
Answer:
allows for the genetic code to be preserved in future generations of cells.
QUESTION
Genetic imprinting
Answer:
is when expression of genetic traits is determined by weather the trait is inherited from the
mother or the father.
