Answer:
Fructose 2,6-bisphosphate is a <em>positive</em> regulator of glycolysis and a <em>negative</em> regulator of gluconeogenesis.
Explanation:
Fructose-2,6-bisphophate is an allosteric effector of the enzymes phosphofructokinase-1, PFK-1 and fructose-1,6-bisphosphatase, FBPase-1.
When fructose-2,6-bisphosphate binds to its allosteric site on PFK-1, it increases the enzymes affinity for its substrate fructose-6- phosphate and reduces its affinity for ATP and citrate, its allosteric inhibitors. This favors favors glycolysis.
However, binding of fructose-2,6-bisphosphate on its allosteric site on FBpase-1 has the opposite effect on it. It reduces its affinity for its substrate, fructose-1,6-bisphosphate, thereby inibiting gluconeogenesis.
Answer:
Chlorophyll gives plants their green color because it does not absorb the green wavelengths of white light. That particular light wavelength is reflected from the plant, so it appears green. Plants that use photosynthesis to make their own food are called autotrophs.
The answer is genetic drift. This is the <span>change</span> of allelic frequency in a population due
to natural selection in <span>favor</span> of particular
traits. The effect of natural drift is <span>greater</span>
is a population of small size that in a big population. When the allelic
frequency of the isolated group of plants reaches 0, it is <span>deemed</span> as lost.
Answer:
8644
Explanation:
there is a difference of 2161 between the numbers. If you multiply the difference by 4, you would get the answer.
