PLZ HELP QUICKLY DUE SOON THXS:) What are the functions of an enzyme in metabolic reaction? (Choose all that apply.)
-bringing substrates closer together so they are more likely to react
-binding to ions to form a substrate
-alligning the parts of substrates that need to connect to form a product.
-lowering the energy it takes for a reaction to occur or speeding up a reaction.

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:

Aligning the parts of substrates that need to connect to form a product.

Lowering the energy it takes for a reaction to occur or speeding up a reaction.

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.

i))the process of preparing food by green plants in the presence of sunlight is called photosynthesis.

ii) leaf is the site for photosynthesis.
