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.
Enzymes are proteins that catalyze chemical reactions by lowering the activation energy required. They have specific active sites that bind to substrates to facilitate the reaction. Enzymes are not consumed in the reaction, allowing them to be reused multiple times.

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.
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 conditions affects the function of enzymes?
Conditions such as temperature, pH, substrate concentration, and enzyme concentration can affect the function of enzymes. High temperatures can denature enzymes, extremes in pH can alter their structure, low substrate concentration can slow down reaction rates, and low enzyme concentration can limit the rate of reaction.
What are four things that can affect the way enzymes work?
Temperature: Enzymes have an optimal temperature range, and deviations from this range can affect their activity. pH: Enzymes function best within a specific pH range, and changes in pH can disrupt their structure and function. Substrate concentration: Enzyme activity is influenced by the concentration of the substrate available for binding. Inhibitors: Molecules that bind to enzymes can either inhibit or enhance their activity, affecting their function.
Describe the structure and function of a fruit?

What does enzymes functions depend on?
The function of an enzyme is dependent on the shape of the enzyme. The structure and shape determines what the enzyme can do.
Which organelle or structure contains enzymes that function best at acidic pH values?
The lysosome
All enzymes function optimally at pH equals 7.4 . true or false?
False. While some enzymes may function optimally at a pH of 7.4, not all enzymes have the same optimal pH. Enzymes can have a range of pH values at which they function best, depending on their specific structure and function.
Describe the structure and function of primary bronchus?
The function is to transport air to the rest of the body.
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.
How is the structure of the endoplasmic related to its function?
The structure of the endoplasmic related to its function by the smooth ER having a high surface area. This allows larger amounts of action and the storage of key enzymes.
What term is used to describe an anatomical structure with no known function?
vestigial
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 is the isoenzyme?
isoenzyme is each of two or more enzymes with identical function but different structure. Hope this Helps.
What type of structure do proteins which act as enzymes possess?
Proteins that act as enzymes typically have a specific three-dimensional structure called an active site. This active site is where the enzyme binds to its target molecule, known as the substrate, to catalyze a chemical reaction. The structure of the active site allows enzymes to be highly specific in their function.
What is the structure of enzymes in living cells?
Enzymes are typically structured as proteins with a specific three-dimensional shape that enables them to bind to and interact with specific molecules called substrates. This structure is crucial for the enzyme's function, as it determines the enzyme's catalytic activity and specificity. Additionally, enzymes may have co-factors or co-enzymes that are necessary for their activity.
