What is enzyme affinity?
Enzyme affinity refers to the strength of binding between an enzyme and its substrate. It determines how readily an enzyme can bind to its substrate and catalyze a reaction. Enzymes with high affinity have a strong binding interaction with their substrates, leading to efficient catalysis.
Can an enzyme continue to ract with other molecules once it has finished reacting with one?
Yes, proteic enzymes are not denatured by reacting with their substrates.
Flexing the head of this molecule provides what is known as the?
Flexing the head of a molecule provides what is known as the active site, where specific interactions occur between the molecule and other substances, such as enzymes and substrates. This flexibility allows for optimal binding and catalytic activity, essential for biological functions.
What effect does cooking have on enzyme activity?
You mean heating the enzymes? heating to a certain degree increases their rate of catalytic activity, until about 30-40 degrees Celsius. However if you continue heating, the enzyme's basic structure will be deformed (it changes shape), and since structure is essential to function, the enzymes activity will be reduced. that happens around 60-70 degrees Celsius, but it is different in various organisms.
What are the most common catalysts in living organisms?
The most common catalysts in living organisms are enzymes. Enzymes are proteins that speed up chemical reactions in cells by lowering the activation energy needed for the reactions to occur. They are specific to particular substrates and play essential roles in metabolism, growth, and other biological processes.
What do enzymes and substrates look like?
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.
What is enzyme affinity?
Enzyme affinity refers to the strength of binding between an enzyme and its substrate. It determines how readily an enzyme can bind to its substrate and catalyze a reaction. Enzymes with high affinity have a strong binding interaction with their substrates, leading to efficient catalysis.
Can an enzyme continue to ract with other molecules once it has finished reacting with one?
Yes, proteic enzymes are not denatured by reacting with their substrates.
What does it mean that enzymes are not changed when they perform their function?
Enzymes are not consumed or altered during a reaction; instead, they speed up reactions by facilitating the conversion of substrates into products without being changed themselves. This ability to be reused distinguishes enzymes from other catalysts.

Flexing the head of a molecule provides what is known as the active site, where specific interactions occur between the molecule and other substances, such as enzymes and substrates. This flexibility allows for optimal binding and catalytic activity, essential for biological functions.
What breaks down enzymes in biological systems?
Enzymes in biological systems are broken down by other enzymes called proteases. These proteases help regulate the activity of enzymes by breaking them down when they are no longer needed.

However if you continue heating, the enzyme's basic structure will be deformed (it changes shape), and since structure is essential to function, the enzymes activity will be reduced. that happens around 60-70 degrees Celsius, but it is different in various organisms.

How could a change in a polypeptide affect cell activity?
Enzymes are derived from polypeptide chains, enzymes are responsible for adequate cell activity. Therefore, if a polypeptide chain is not properly composed, the enzyme will be dysfunctional, hence leading to a depletion in cell activity.
What other main functions do proteins serve?
as enzymes to control the rate of reactions and regulate cellular activity
What 2 things can enzymes do to a substrate?
Speeds up the rates of chemical reactions by providing energy for the cell to use. Thus, the cell is not working as hard to perform the task. You need enzymes to survive. That is one of the reasons why a high temperature fever is a problem, the enzymes that help to keep you alive are denaturing (basically being rendered useless) and without them you cannot live.
How does enzyme concentration affects the rate of enzyme action?
it slows down the reaction time of the enzyme because there are too many substrates bumping into each other and make it harder for them to bind to the enzymes.
