What are the functions of an enzyme in a metabolic reaction? (Choose all that apply.) aligning the parts of substrates that need to connect to form a product.
Obringing substrates closer together so they are more likely to react
binding to ions to form a substrate
lowering the energy it takes for a reaction to occur or speeding up a reaction

In a metabolic reaction an enzyme has the function of:

Explanation:

Enzymes are biological catalysts of a protein nature, in charge of decreasing the energy needed for a metabolic reaction to occur.

One of the characteristics of enzymes is their specificity for a substrate. The union between the enzyme and the substrate occurs when the substrate binds to a place in the enzyme called the active site. For this to occur, the enzyme adapts the configuration of its active site so that it attaches to the substrate, functioning like a key in a lock.

The main function of the enzyme is to make a reaction faster and to reduce the amount of energy needed for that reaction.

For this reasons enzymes can:

The other options are wrong because:

    - It is not an enzymatic function to bring the substrates closer together so that they can react.

    - Enzymes do not bind to ions to form substrates, they bind to a substrate to obtain a product.

looks like the answer is     c     to me!

it marks things for degradation via the proteasome. it alters there celluar location.
