|
The shape of an enzyme’s active site matches the shape of its substrate
|
|
|
Enzymes are used up in biological reactions
|
|
|
Enzymes work faster at higher temperatures
|
|
|
Every enzyme has one specific substrate that it breaks down or builds up.

Detailed explanation-1: -This statement about enzymes is true: Enzymes accelerate reactions by lowering the activation energy. Enzymes are proteins whose three-dimensional form is key to their function. Enzymes do not alter the overall change in free energy for a reaction.
Detailed explanation-2: -Enzymes are proteins that help speed up metabolism, or the chemical reactions in our bodies. They build some substances and break others down.
Detailed explanation-3: -Enzymes bind substrates at key locations in their structure called active sites. They are typically highly specific and only bind certain substrates for certain reactions.
Detailed explanation-4: -There may be one or more substrates for each type of enzyme, depending on the particular chemical reaction. In some reactions, a single-reactant substrate is broken down into multiple products. In others, two substrates may come together to create one larger molecule.
