Penicillin Allergies

Saludos, How are some people allergic to penicillin? My hypothesis (humurous) Some individuals have in common some enzymes with bacteria. (Let's call it Enzyme A) These are the same enzymes that bacteria use to build its cell wall. By consuming penicillin, competitive enzyme inhibitors block the act...

I just figured out that the answer to my question is "yes." An enviromnment that's too acidic or too basic relative to that of the enzyme's habitual environment WILL denature the enzyme. However, how exactly does it denature the enzyme in this case? I know that if too much thermal energy is absorbed...

Denaturing Enzymes

Saludos,

Do human enzymes denature when the pH is too low or too high from their habitual pH range? If they don't, then what happens to them?

Thank You,

Furthermore, in biological systems high temperatures would harm the cell more than it would aid it. High temperatures kill cells and denatures proteins. That's why enzymes exist. They lower the amount of Activation Energy needed. This means that it lowers the amount of heat needed to activate a reac...

Re: Activation energy

I know what activation energy is and what it does but my question is - can activation energy be anything? (I know it can't be anything but what are the different kinds of activation energy?) Saludos, I just finished reading the section about activation energy and my textbook highlights that usually...

Exergonic Reaction

Saludos,

Why is it that an exergonic reaction is coinsidered spontaneous (no need of outside energy) when it clearly needs thermal energy to activate the reaction?

Thank You,

Hello, I agree with the rest of the foreros that facial hair isn't as good as you think. I remember I used to be so anxious about growing facial hair so I could look older or simply acquire a different look by matching it with my eyebrows and hair. However, now that I finally grew some it is annoyin...

ATP ASAP

Hello, How exactly does Adenosine Triphosphate (ATP) provide energy to other molecules? I know that energy is released when ATP becomes ADP because the phosphates groups are all negatively charged, therefore they repel each other and want to break away and be as far apart from each other as quickly ...
