The active site.
The active site.
Enzymes attach to things called substrates to help speed up the reaction. Only certain enzymes match the shape of certain substrates.
Enzymes are proteins that have a very specific structure. The region on the surface of an enzyme that is responsible for binding and converting the subtract into the product is called the active site.
Im not here to answer your homework questions for Mrs Gerehearts class. LOLOL
Substrates
Enzymes interact with substrates by binding only with specific substrates. Enzymes will then alter the shape of the substrate in order to induce reaction.
They actually bind to a substrate as the term reactant is usually used in chemistry. They fit into what we call an active site just like a key will fit into a lock. The key must be the correct key or the reaction will not occur. So the enzyme is said to be specific for that substrate.
Substrates
These molecules are called substrates.
Yes, most enzymes are smaller in size compared to their substrates. Enzymes typically have specific active sites where they bind with their substrates to catalyze chemical reactions. This specific interaction allows enzymes to facilitate reactions despite being smaller in size.
True. Enzymes are highly specific in their interactions with substrates. Each enzyme is designed to interact with a particular substrate based on the shape and chemical properties of both the enzyme and the substrate. This specificity allows enzymes to catalyze specific reactions efficiently.
Enzymes and substrates are molecules and look like any other molecules. In case of enzymes specifically, they are proteins and so have long chains of amino acids folded into different structures and shapes.
