Answer:

A. COAGULATION

Explanation:

Hemostasis is stopping bleeding. To prevent or keep blood in the blood vessels due to damage of the vessels.

Three steps are important in hemostasis;

1. Vasoconstriction : which is the contraction of the smooth muscles of the blood vessels reducing the amount of blood flow to the area of damage and thereby blood loss.

2. Platelet Plug Formation: this is the function of platelet in the blood. It attaches to the damaged endothelium and form a plug.

3. Coagulation/ Clotting : this is the release of clotting factors to the surface of the damaged vessel.

Fibrin is a major component of the clotting factor.

So therefore, coagulation is a process in hemostasis. Formation of platelet plug is a stage also and not the formation of platelet in the blood.

Kisachek [45]

Answer:

Part A It is associated with peroxisomes and mitochondria.

Part B. It is associated with smooth endoplasmatic reticulum.

Explanation:

The oxidation of long chain fatty acids are produced at the beginning in the mitochondria, it is called B oxidation because there is a carbon in this position that in this process is going to be oxidized to a carbonyl group. The very long fatty acid chains are also oxidized in the peroxisomes.

The cholesterol biosynthesis is made inside the hepatic cells, in the endoplasmatic reticulum. Is a process that starts with acetyl Coenzime A that was oxidized in the mitochondria. This process is regulated by the intake of cholesterol from the diet.

Hope this info is useful.

VARVARA [1.3K]

Answer:

It could be prevent Ga from binding to the epinephrine receptor.

Explanation:

Hindering GTPase action will make G-protein to tie to adenyl cyclase for all time so Glucose is delivered persistently.  

Diminishing the proclivity for GDP will build the opportunity of authoritative of GTP to G protein which thus will initiate the pathway.  

On the off chance that G protein ties with adenyl cyclase it will invigorate it.  

Yet, in the event that the G-protein is kept from official with epinephrine receptor, at that point the receptor can't enact trade the guanine nucleotide to G-protein for initiation. Thus the G-protein stays in latent state.
