Answer:

The intracellular chemical reaction will proceed at a slower rate.

Explanation:

Enzymes are proteinous substances referred to as "biological catalyst". Enzymes catalyze biochemical reactions by increasing the rate at which the reaction occurs. They do this by lowering the activation energy needed for the reaction to start.

Since enzymes speed up the rate of chemical reactions, an absence of such enzyme or its non-functionality will result in such reaction proceeding at a slower rate.

The half life of tritium is 12.3 years. How much sample will remain if you start with 425g of tritium that is found after 4 half
natta225 [31]

Answer:

26.56g

Explanation:

The half life of an isotope decay is the time transcurred when the initial amount of the isotope decays to the half of its amount.

For the problem, when 1 half life transcur, the sample has a mass of:

425g / 2 = 212.5g

When 2 half lives transcur:

212.5g / 2 = 106.25g

3 half lives:

106.25/2 = 53.13g

And the amount that is found after 4 half lives is:

53.13/2 =

<h3>26.56g</h3>

Trava [24]

Answer:

55g NH₄Cl / 100g Water

Explanation:

Solubility of a substance define the amount of solute per solvent in a saturated solution. The solution can dissolve additional solute if heated.

In the problem, as the first crystal appears at 61°C the solubility in this temperature is the concentration of the solution, that is:

2,75g NH₄Cl / 5,0g water ₓ 100 = <em>55g NH₄Cl / 100g Water</em>

What are the similarities between the adrenal hormone cortisone and the synthetic corticoid prednisone?
vaieri [72.5K]

Answer:

Options a,b, c and d are correct

Explanation:

From the diagram attached in the picture below, They both have steroid nucleus since they have functional groups (such as the methyl and the ketone groups) that are spatially attached. It can also be deduced that both structures have three (3) ketone groups (CO/C=O), two (2) methyl groups (CH₃) and two (2) hydroxyl groups (OH). Hence, options a, b,c and d are correct.

However, cortisone has one (1) double bond while prednisone has two (2) double bonds.
