Catalyst increases the rate of reaction without being consumed by it. In addition, while the catalysts lower the activation energy, it does not change the energies of the original reactants nor products. Rather, the reactant energy and the product energy remain the same and only the activation energy is altered.The key importance of activation energy is that collisions only result in a reaction if the particles collide with enough energy to get the reaction started. This minimum energy required is called the activation energy for the reaction.

What are two protein classes based on structure and function in the body?
Two protein classes based on structure and function in the body are enzymes and structural proteins. Enzymes are involved in catalyzing chemical reactions, while structural proteins provide support and strength to cells and tissues within the body.
Denatured enzymes are the same as?
Denatured enzymes are enzymes whose structure has been altered, leading to loss of their original function. They lose their ability to catalyze reactions efficiently or at all due to changes in their shape or folding. This can be caused by factors such as temperature, pH, or exposure to chemicals.
What happens to enzymes at low pH levels?
At low pH levels, enzymes can become denatured, meaning their structure and function can be disrupted. This can lead to a decrease in enzyme activity and effectiveness.
Which structure-function pair is mismatched?
A mismatched structure-function pair would be the function of the pancreas as a muscle for movement. The pancreas is actually an organ responsible for producing digestive enzymes and hormones such as insulin, rather than being involved in movement.
What is the significance of the three-dimensional structure of a protein in relation to its function and interactions within a cell?
The three-dimensional structure of a protein is crucial for its function and interactions within a cell. This structure determines how the protein can bind to other molecules, such as enzymes or receptors, and carry out specific tasks. Changes in the protein's structure can affect its function and ability to interact with other molecules, leading to potential disruptions in cellular processes.
