Answer:
Mg is able to give off two of its electrons to other molecule, not four. ATP, in this case is the aceptor of those electrons
Two correct answers are:
1) Hexokinase cannot bind active ATP when it is not complexed with Mg2+
2) Mg2+ makes the terminal phosphorus atom of ATP more accessible to nucleophilic attack by a glucose-OH group
Explanation:
As Mg occurs naturally as ion Mg++, it is able to give off only two of its electrons to other molecule, then it is possible for ATP to receive two electrons of Mg, forming MgATP2-
The hexokinase reaction, here cited, corresponds to the glucose phosphorylation of its sixth carbon to produce glucose-6-P, which is a glycolysis intermediate. In this way glucose is activated (ATP is initially invested to energize glucose). Later on, Glyceraldehide-3-P is produced, and finally converted to pyruvate, NADH2 and ATP
answer:
Where would you expect to find the kelp forest, a type of algae, pictured here and why? Algae live only in the epipelagic zone because it is the only zone with enough light for photosynthesis. During an El Niño year, there is increased precipitation in the Southern United States, but the north is warmer and dry

Answer:
Chromosome number variation: B. Down syndrome
Loss-of-function allele : D. PKU
Physiological trait
: E. Lactose metabolism
Discovery-based science
: A. Human Genome Project
Genetic cross: C. Model organism
Explanation:
Down syndrome is a condition in which there is an extra copy of the chromosome number 21. Hence, it is a chromosome number variation.
Physiological traits refers to any function of a body. Hence, it matches with lactose metabolism.
Human Genome Project was a project under which the whole genome of the humans were sequenced. Hence, it is a discovery based science.
A genetic cross is made between model organisms to test for the offsprings that would be produced from a cross. Hence, genetic cross and model organism math with each other.

Question :</h2>
Which of the following is not a function of cerebrospinal fluid?
A) acts as a transport medium for waste products
B) provides cushioning for delicate neural tissues
C) provides buoyant support for the brain
D) produces ATP for impulse transmission
E) acts as a transport medium for nutrients
Answer:
D) produces ATP for impulse transmission
Explanation:
CSF doesn't produce ATP for the impulse transmission hence option D is the right option.
Cerebrospinal fluid (CSF) performs following functions :
1) Protects the brain and spinal cord from trauma
2) It supplies nutrients to the nervous tissues
3) It removes the waste products from cerebral metabolism.
