Enzymes speed up reactions by

Question

Accepted Answer

B. lowering the activation energy of the reaction

An enzyme reduces the activation-energy barrier by holding substrates in a favourable geometry and stabilising the transition state.
The enzyme itself is unchanged.
Substrate concentration is set by the cell, not the enzyme
reactions don't get energy 'from' the enzyme
product stability depends on the reaction, not the catalyst.

Answer

raising the concentration of substrate inside the cell

Answer

providing reaction energy directly

Answer

making the products less stable
