Plant leaves are organs that are composed of multiple cell types, including palisade cells and guard cells. Palisade cells conta

in many chloroplasts and are the main sites of photosynthesis in a leaf. Guard cells are specialized epidermal cells that can change shape in order to control gas exchange between the leaf and its surroundings.

(Choice A)
A
The various cell types found in a leaf have unique, specialized functions.

(Choice B)

When an animal confronts a "fight-or-flight" situation, the release of epinephrine promotes glycogen breakdown in the liver, hea
nika2105 [10]

Answer: and Explanation:

A.)The reason for the different products of glycogen breakdown in the two tissues is that glucose 6-phosphotase which is

a known enzyme that brings about hydrolysis of glucose 6-phosphate as a result of the creation of a phosphate group and free glucose is not available in heart and skeletal muscle, therefore,any glucose 6-phosphotase that is produced will just enters the glycolytic pathway and get converted to lactate through pyruvate, in the absence of Oxygen O2.

B) Whenever a situation involving fight or flight arises, the concentration of glycolytic precursors becomes high in order to prepare for muscular activity. Since the membrane is impermeable to any charged species, and at the same time glucose 6-phosphotase enzyme cannot be moved through the glucose transporter, then there cannot be a release of Phosphorylated intermediates from the cell. The blood glucose level must be maintained by the liver by releasing of glucose.

glucose that is later formed from glucose 6-phosphotase then enters the bloodstream.
