julia-pushkina [17]

A Biochemist is a type of chemist understands the structure of living systems and, in turn, their functions and ways to control them.

<h3>What is the chemistry of living systems called?</h3>

The chemistry of living system is known as Biochemistry.

Biochemistry is a study of the chemical changes that occur in living organisms.

Scientists that study biochemistry are called Biochemists.

Biochemistry studies the structure and function of biological molecules such as carbohydrates, lipids, proteins, e.t.c., as well the chemical reaction they undergo.

Biochemistry also studies the energy changes that occur in living systems.

In conclusion, the chemistry of living systems is called Biochemistry.

Suppose that a certain biologically important reaction is quite slow at physiological temperature (37 oC) in the absence of a ca
Oksi-84 [34.3K]

Answer:

30 kJ

Explanation:

Arrhenius equation is given by:

k=Aexp(-Ea/RT)\\

Here, k is rate constant, A is Pre-exponential factor, Ea is activation energy and T is temperature.

taking natural log of both side

ln k = ln A - Ea/RT

In Arrhenius equation, A, R and T are constant.

Therefore,

ln\frac{k_2}{k_1} =\frac{Ea_1-Ea_2}{RT}

Ea_1-Ea_2 is the  lowering in activation energy by enzyme,

R = 8.314 J/mol.K

T = 37°C + 273.15 = 310 K

\frac{k_2}{k_1} =1\times 10^5

ln 1\times 10^5 =\frac{Ea_1-Ea_2}{RT}\\{Ea_1-Ea_2} = 11.512 \times 8.314 \times 310\\=29670\ J\\=30\ kJ
