The optimal temperature for an enzyme is the one at which the enzyme is the most active and productive.

At temperatures below the optimum temperature, the enzyme still catalyzes the reactions, but with decreased activity.

Even though the temperature increase increases the activity of the enzymes, temperatures that are greater than the optimum cause damage the enzyme strucutre, causing denaturation and loss of function

Answer:

The enzyme will denature.

Explanation:

Enzymes are defined as bio catalyst that can increase the rate of a biochemical reaction occurring in the living organisms. Enzymes increases the effective collision between the reactants.

Enzymes works at optimum temperature and pH. The enzyme gets denatured and loses its biological activity if temperature varies too far. The enzyme structure will distort due to high temperature. Most of the enzymes are made up of proteins. High temperature can destroy the folded structure and the shape of the enzyme.

Tartaric acid, C4H6O6, has the first ionization constant with the value: Ka1 = 9.20 × 10-4. Calculate the value of pKb for the c
nirvana33 [79]

Answer:

pKb = 10.96

Explanation:

Tartaric acid is a dyprotic acid. It reacts to water like this:

H₂Tart  +  H₂O  ⇄  H₃O⁺   +  HTart⁻         Ka1

HTart⁻  +  H₂O  ⇄  H₃O⁺   +  Tart⁻²           Ka2

When we anaylse the base, we have

Tart⁻²   +  H₂O  ⇄  OH⁻  +  HTart⁻       Kb1

HTart⁻  +  H₂O  ⇄  OH⁻  +    H₂Tart          Kb2

Remember that Ka1 . Kb2  = Kw, plus pKa1 + pKb2 = 14

Kb2 = Kw / Ka1  →   1×10⁻¹⁴ / 9.20×10⁻⁴  = 1.08×10⁻¹¹

so pKb = - log Kb2   → - log 1.08×10⁻¹¹ = 10.96
