Answer:
D. Allosteric activator
Explanation:
In an enzyme, the allosteric site is a site/motif different from the active site, (i.e., the site with catalytic activity) which is able to interact with regulatory effector molecules in order to activate or inhibit enzymatic activity by influencing the tridimensional (3D) structure of the enzyme. An allosteric activator is an effector molecule with the ability to bind to a specific enzyme at a different site than the active site, thereby modifying the shape of the enzyme and increasing the affinity of this enzyme for its substrate. Moreover, Adenosine monophosphate (AMP) is a nucleotide composed of a phosphate group, a sugar ribose, and an Adenine (A) base. This effector molecule (AMP) has shown to allosterically stimulate diverse enzymes in physiological conditions (e.g., AMP-activated protein kinase).
Answer:
Although the drop-down boxes are not shown, I will answer the question as follows:
The etymology of the word pericardium comes from the Greek perikardion; Greek prefix "peri" meaning "around" and the suffix "cardio" meaning "heart"
With this information you can solve the question.
Explanation:
The pericardium is a double layer where the heart is lodged. It has two membranes: the fibrous pericardium and the serous pericardium. The fibrous pericardium is formed by connective tissue. Its function is to protect the heart from the outside, it also allows you to join it with the heart cavity. While the serous pericardium is a bag where the myocardium is lodged. It consists of two layers: the visceral layer, joins the heart muscle, and the parietal layer, attached to the serous pericardium.
Peer review and reapeted experimental values. Please tell me if this helps you.
It seems that you have missed the necessary options to answer this question, but anyway, here is the answer. The cell walls of bacteria contain the material PEPTIDOGLYCANS. This is the <span>substance forming the cell walls of many bacteria, consisting of glycosaminoglycan chains interlinked with short peptides. Hope this answer helps.</span>
