Can you elaborate after choosing?

-fibrosis patient may suffer
a- the non-occurrence of blood clotting when exposing to air

b- thd blood clotting inside the blood vessels

c- the blood clotting when exposed to air

d- the occurrence of clots inside the blood vessels and they are not occurred when exposing to air

Fibrosis patient may suffer from the blood clotting when exposed to air

c- the blood clotting when exposed to air

Explanation:

Fibrosis is the development of excess fibrous connective tissue in an organ or in a reparative or responsive procedure. It is a sort of interstitial lung illness. It is brought about by lung tissue getting thick and solid and in the long run framing scar tissue inside the lungs.

Platelets ordinarily start the thickening procedure when they'reexposed to the air, for example, in a cut or wound. Blood clumps structure when certain pieces of your blood thicken, shaping a semisolid mass. This procedure might be activated by damage or it can here and there happen inside veins that don't have conspicuous damage.

In people, cell parts make up roughly 45 percent of the blood and the fluid plasma 55 percent. Be that as it may, some of the time blood clumps structure too effectively or doesn't break down appropriately and travel through the body restricting or blocking bloodstream. This is called over the top blood thickening or hypercoagulation and can be perilous and prompts Fibrosis.

this is a good question! i'll do some research and come back when i have the answer!

answer: substrate concentration. enzymes work best when there is a high enough substrate concentration for the reaction they catalyse.
