What is feedback inhibition?
How does feedback inhibition affect enzyme activity?
How does feedback inhibition affect amino acid production?
Feb 12, 2017 · Feedback inhibition is a cellular control mechanism in which an enzyme’s activity is inhibited by the enzyme’s end product. This mechanism allows cells to regulate how much of an enzyme’s end product is produced.
Feedback inhibition. Key metabolic enzymes are often inhibited by the end product of the pathway they control (feedback inhibition). In the rest of this article, we'll examine these factors one at a time, seeing how each can affect enzyme activity.
- Allosteric regulation confuses me a lot. I don't really get it even after I watched the video on Kha...I'll try an analogy — let me know if this helps. Imagine that an enzyme is like tiny sculpture made from a wire twisted into a very complicated, bu...
- In school, we conducted an experiment where a small piece of paper dipped in a liver solution was dr...This is because the liver cells contain enzymes called catalase which speed up the breaking down of hydrogen peroxide into water and oxygen. When t...
- What is an allosteric activator?A molecule that attaches to the enzyme at a site (not the active site), changing the configuration of the enzyme, which allows the substrate to att...
- whats the difference between non competitive inhibition and allosteric regulation(involving inhibito...Allosteric regulation and noncompetitive inhibitor bind to site other than active site but allosteric regulation change the conformation of enzyme...
- The information about noncompetitive inhibitors contradicts what Sal said in his videos: "Competitiv...I think Sal is right about Competitive Allosteric Inhibition. In CAI, the inhibitor binds to an allosteric site (somewhere on the enzyme that is no...
- if a allosteric inhibitor casues distortion of the enzyme's shape so that it cannot function, is it ...Being *allosteric* lets you know that the inhibitor binds somewhere other than the *active site*, where the substrate binds. The location that the...

- Life is a process regulated by enzymes. What might be the sources of these enzymes? If particular en...Enzymes are encoded as genes in the DNA — these genes are then transcribed to produce RNA and (for most enzymes§) then translated† to make a protei...
- How do you determine whether an enzyme's activity is enhanced or inhibited by regulatory cell bindin...You follow up with the next steps. If reactions proceeds - it was activation, otherwise it must be some kind of inhibitor. :D
Feedback inhibition, where the end product of the pathway inhibits an upstream process, is an important regulatory mechanism in cells. The production of both amino acids and nucleotides is controlled through feedback inhibition.

Negative feedback results in the inhibition of an enzyme in a biochemical pathway, reducing the activity of earlier enzymes, and stopping the pathway. Positive feedback results in the activation of more enzymes, thus increasing its production of the product.
May 18, 2016 · Feedback inhibition, where the end product of the pathway inhibits an upstream process, is an important regulatory mechanism in cells. The production of both amino acids and nucleotides is controlled through feedback inhibition.
Nov 22, 2023 · Negative feedback results in inhibition, but another powerful tool in biological systems is the positive feedback cycle. This process is the opposite of negative feedback. We can find an example of it in catalytic cascade processes, such as blood clotting.
