Answer:
b. Phosphofructokinase; Fructose-1,6-bisphosphatase
Explanation:
Glucagon is a hormone which functions to initiate gluconeogenesis whwreas insulin functions to initiate glycolysis.
Fructose-2,6-bisphosphate (F26BP) is an allosteric regulator of the <em>glycolytic and gluconeogenic enzymes phosphofructokinase-1 (PFK-1) and fructose-1,6-bisphosphatase (FBPase-1).</em>
It stimulates glycolysis and inhibits gluconeogenesis by binding to its allosteric site on phosphofructokinase-1 reducing its affinity for the allosteric inhibitors ATP and citrate .
It is formed by phosphorylation of fructose-6-phosphate catalyzed by <em>phosphofructokinase-2</em> and is broken down by <em>fructose-2,6-bisphosphatase </em>which are two separate enzymatic activities of a single, bifunctional protein (PFK-2/FBPase-2).
Phosphorylation of PFK-2/FBPase-2 due to glucagon release enhances its FBPase-2 activity thereby stimulating gluconeogenesis and inhibiting glycolysis.
Dephosphsorylation of PFK-2/FBPase-2 due to insulin release enhances its PFK-2 activity, thereby stimulating glycolysis and inhibiting gluconeogenesis.
That would be D. A male with one recessive allele.
Squares represent males and circles represent females. This male has gotten 1 recessive allele from her mom(her genotype is aa because she is expressing the recessive trait).
Answer: Yes, many plant cells have both mitochondria and chloroplasts!
Hope this helped! :D
I honestly think it Lymph,
Short answer: The apple tree is the producer, the cardinal is the consumer, and the caterpillar is the decomposer.
Long answer: The tree produces energy, and when the caterpillar eats the leaves/apples, that keeps the caterpillar fed, then the cardinal comes along and eats the caterpillar, then when the cardinal dies, an apple tree can grow in it's place, keeping the cycle going. hope that hels!p
