Enzymes Flashcards
Structure of a protein
1st- chain Of amino acid
2nd helix or pleated sheets
3rd- 3d tertiary
4th
Proteins
Amino acids held together by peptide bonds.
No catalyst make what?
A reaction occur that can’t otherwise occure.
What does an enzyme do?
It just increases the rate of the reaction.
What does an enzyme do to the activation energy?
Lowers it
Describe energy released from a reaction.
It is the same with or without an enzyme
But the amount of time will change.
All ____ are _____ but not all ____ are ____.
Enzymes
Proteins
Proteins
Enzymes
Reaction =
Substrate
Enzyme- substrate complex
When the substrate and enzyme connect at the active site.
Enzymes can change while bound to substrate but however….
But they will change back to their initial form
What is the induce fit?
The slightly change to make a tight fit
Describe the enzyme helpers
- Cofactors, inorganic ions ex: copper iron zinc
- Coenzymes, Corbin containing
- Prosthetic (fake) group, permanently bound to the enzyme ex: heme, flavin
RNA can also act as what
Catalysis
Enzymes are usually used with what?
Pathways/ cycles interconnecting
How can a cell maintain homeostasis
by regulating the activity of an enzyme
Does this by natural inhibitors- occurs to regulate metabolism
