Answer:
All of the above.
Explanation:
Regulation of the expression of genes refers to different processes tge cells use to increase or decrease the production of some gene content. It involve Turing gene on and off so as to ensure that appropriate genes are expressed at the right times. This allow organism to respond to changes in their environment.
ITS B Chloroplast,!! mah dude the ugly leaf thingy produces atp for photosynthesis also known for its photosynthesis
<span>The tissue is a group of structurally and functionally similar cells and their extracellular matrix. Grouping of those similar cells enables them to carry out a specific function. In the hierarchy of structural organisation tissue is level between cells and a complete organ. Functional grouping together of multiple tissues forms an organ.</span>
Answer:
a. inhibits cAMP phosphodiesterase, the enzyme that converts cAMP to AMP.
Explanation:
The phosphodiesterases are a group of enzymes that are capable of breaking phosphodiester bonds such as those between nucleotides in nucleic acids. The Cyclic adenosine monophosphate (cAMP) is a second messenger involved in intracellular signaling pathways. This molecule (cAMP) is hydrolyzed by the cAMP-dependent phosphodiesterase, which catalyzes the enzymatic breakdown of phosphodiester bonds (i.e., hydrolyzing cAMP to 5-AMP). The cAMP levels are modulated by the balance between its generation and the degradation via cyclic nucleotide phosphodiesterase.
