Which statement is true regarding the function of a catalyst in a chemical reaction? enzymes are biological catalysts capable of decreasing the rate of specific biochemical reactions by many orders of magnitude. a catalyst is consumed by the reaction. a catalyst decreases the rate of a reaction. a catalyst provides an alternate mechanism for the reaction.

.A catalyst provides an alternate mechanism for the reaction

Explanation:

The catalyst provides a mechanism of reaction having the lowest activation energy. It lowers the energy barrier between reactants and products hence it increases the rate of reaction by several orders of magnitude

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be
