Answer:

Image result for what is an inhibitor? * A molecule that blocks an enzymes active site A molecule that destroys substrate A molecule that is made out of lipids A molecule that allows the chemical reaction to speed up

An enzyme inhibitor is a molecule that binds to an enzyme and decreases its activity. ... The binding of an inhibitor can stop a substrate from entering the enzyme's active site and/or hinder the enzyme from catalyzing its reaction. Inhibitor binding is either reversible or irreversible.

I hope this helped :)

Renin hydrolyzes angiotensinogen, which is released from the _________, to form angiotensin i.

tia_tia [17]

Renin is an enzyme that helps control blood pressure and regulate levels of sodium and potassium in the body. Angiotensinogen is the hormone that causes the narrowing of blood vessels. It is released from liver to form angiotensin.

<h3>What is the role of angiotensin?</h3>

Angiotensinogen is a hormone that on hydrolysis forms angiotensin

Angiotensinogen is hydrolyzed by renin enzyme and forms angiotensin.

This angiotensin helps to increase blood pressure by the process of vasoconstriction, increased aldosterone biosynthesis and renal actions.

Thus, it can be concluded renin hydrolyzes angiotensinogen, which is released from the liver, to form angiotensin.

High doses of caffeine interfere with the dna replication checkpoint mechanism in mammalian cells. why then do you suppose the s

Kipish [7]

Molarity = $\frac{Solute(in Moles)}{Solution (in Liters)}$

Moles of Caffeine = Mass of Caffeine/Molar Mass
Mass = 100 mg = 0.1 g
Molar Mass = 196 g/mole

Moles of Caffeine in one cup = 0.1/196 moles
= 5.102 * 10^-4 moles

If one cup of coffee is ingested (A typical adult contains about 40 liters of water),

Molarity of caffeine = [(5.1 * 10^-4)/ 40] M
= 0.012755 mM

The toxic molarity of caffeine in the body 10mM

How many cups will be toxic?
= Toxic Molarity/ Molarity of 1 cup
= 10/ 0.012755
= 784

In other words, you would have to drink 784 cups of coffee to reach the dose required to interfere with the DNA replication checkpoint mechanism.
