During the course of a catalytic reaction Substrate is covalently bound and oriented with proximity to the active site residues.

The type of chemical species which can facilitate these reactions is transition metal cations.

<h3>What is an Enzyme?</h3>

These are proteins that act as biological catalysts and accelerate chemical reactions.

They function by binding to the substrate and requires the use of transition metal cations which acts as cofactors.

If it takes 7,529 calories of heat to warm 750.0 grams of water, what was the temperature change? The specific heat of water in

Zigmanuir [339]

Answer:

The temperature change was 10.04 °C.

Explanation:

Calorimetry is the measurement and calculation of the amounts of heat exchanged by a body or a system. In this way, there is a direct proportional relationship between heat and temperature. The constant of proportionality depends on the substance that constitutes the body as on its mass, and is the product of the specific heat by the mass of the body. So, the equation that allows calculating heat exchanges is:

Q = c * m * ΔT

Where Q is the heat exchanged by a body of mass m, made up of a specific heat substance c and where ΔT is the temperature variation.

In this case you know:

Q= 7,529 calories (cal)

c= 1 $\frac{cal}{g*C}$

M=750 grams

Replacing:

7,529 cal= 1 $\frac{cal}{g*C}$ *750 g* ΔT

Solving you get:

ΔT= $\frac{7,529 cal}{1 \frac{cal}{g*C}*750 g }$

ΔT= 10.04 °C

So, <u><em>the temperature change was 10.04 °C.</em></u>
