Question

Chemical reactions can occur when sufficient ____________ is supplied to overcome the activation energy. In the lab, heating a mixture of ____________ often overcomes the activation energy. An elevation in temperature ____________ the kinetic energy of the molecules. This provides enough energy to ____________ chemical bonds. This is not feasible in living cells because a change in temperature of this type will cause the proteins to ____________ and cause cell ____________ . To assist with this problem, cells use biologically active protein catalysts called ____________ to facilitate chemical changes.

Answer 1

Chemical reactions can occur when sufficient heat is supplied to overcome the activation energy. In the lab, heating a mixture of substances often overcomes the activation energy. An elevation in temperature increase kinetic energy of the molecules. This provides enough energy to break chemical bonds. This is not feasible in living cells because a change in temperature of this type will cause the proteins to disintegrate and cause cell death. To assist with this problem, cells use biologically active protein catalysts called enzymes to facilitate chemical changes.

Answer 2

Answer:

See explanation

Explanation:

Chemical reactions can occur when sufficient _______energy_____ is supplied to overcome the activation energy. In the lab, heating a mixture of _____reactants_______ often overcomes the activation energy. An elevation in temperature ____increases________ the kinetic energy of the molecules. This provides enough energy to ____break________ chemical bonds. This is not feasible in living cells because a change in temperature of this type will cause the proteins to ______denature______ and cause cell _____die_______ . To assist with this problem, cells use biologically active protein catalysts called ____enzymes________ to facilitate chemical changes.
