Epinephrine causes the enzyme glycogen phosphorylase to break down glycogen within a cell. Epinephrine performs this task on int
SIZIF [17.4K]

Answer:

The fact that it reveals is that:

Epinephrine binds to the receptor tyrosine kinase on the cell membrane and does not act on glycogen phosphorylase.

Explanation:

In cellular respiration, epinephrine is a neurotransmitter and a plasma membrane hormone receptor.  It is not a lipid-derived hormone, but rather an amino acid-derived hormone. As a result, they are unable to pass through the plasma membrane of cells. They bind to receptors on the outer surface of the plasma membrane through plasma membrane hormone receptors (receptor's tyrosine kinase of the cell membrane) because they are lipid insoluble hormones.

Unlike steroid hormones, lipid insoluble hormones (epinephrine) do not directly influence glycogen phosphorylase or the target cell because they cannot enter the cell and operate directly on DNA. The activation of a signaling pathway occurs when these hormones attach to a cell surface receptor; this activates intracellular activity and performs the hormone's specific effects. Nothing crosses through the cell membrane in this fashion; the hormone that binds at the cell's surface stays at the cell's surface, while the intracellular component stays within the cell.

Darya [45]

Answer:

Option A , Genome

Explanation:

Microarrays that contains array of single stranded DNA are used to study thousands of gene expression for all the genes of a genome and are usually termed as DNA miscroarrays. These microarrays being single stranded allows attachment of complementary DNA strand to bind to their surface. The mRNA from the cell is extracted and converted into cDNA which is further used for DNA cloning.

Hence, option A is correct

Under what environmental conditions would a zygote not undergo meiosis
sashaice [31]

A zygote will not undergo meiosis in an environmental state that is not favorable for the zygote’s survival i.e. the chance of the zygote to survive is not certain. Take for example, chlamydomonas will form a zygote under normal asexual mitotic reproduction in a favorable environmental condition. However, under unfavorable environmental conditions the organism also reproduce sexually to form a zygote but will never proceed to meiotic division because of the unfavorable environmental state.
