Re: Enzymes and activation energy.

... So I really think you answered the question in your first paragraph. An enzyme’s selective three dimensional shape, brings the reactants (or substrates) closer together into its active site, This is the alternative route, and: allowing the chemical bonds to weaken and change with less energy ...

Enzymes and activation energy.

... the activation energy in 2 distinct ways: i. Lowering required energy: An enzyme’s selective three dimensional shape, brings the reactants (or substrates) closer together into its active site, therefore allowing the chemical bonds to weaken and change with less energy. An enzyme therefore lowers ...

But in peroxisomes, there are also H2O2 producing reactions going. Where else? And another question, how easily does H2O2 diffuse across ...

Enzymes... Particularly lactase.

... summary of how enzymes work. Here's what I'm having trouble understanding. 1. The video is an anabolic reaction - it's building a molecule from substrates. Is there any way to tell from the video whether it is endergonic or exergonic? I'm guessing it's endergonic because anabolic reactions require ...
