Chapter 8 Flashcards
(18 cards)
All chemical reactions within the body
Metabolism
The breakdown of complex molecules
Catabolism
The synthesis of complex molecules
anabolism
Organisms that obtain their energy from light are called….
Phototrophs
Organisms that obtain their energy from chemical compounds
Chemotrophs
Identify three cellular electron carriers
-FAD/FADH2
-NAD+/NADH
-NADP+/NADPH
Explain the electron carriers’ function
Electron carriers will accept the ions (H+) that are products of the breakdown of complex molecules
Where do electron carriers carry H+ to?
they form a chain that will weave in and out of the bilayer of the cell charging it in order to turn ADP to ATP.
what enzyme helps with the synthesis of ADP to ATP?
ATP synthases
where does the synthesis of ATP take place?
In the mitochondria
What is ATP considered within the cell?
the main energy currency of the cell
Explain the function of a catalysts?
A catalyst, also known as an enzyme, increases the rate of chemical reaction inside the cell. it lowers the energy that is required for that reaction to continue.
What part of the enzyme does a substrate bind to it?
The active site
Explain induced fit
induced fit happens when a substrate binds to the active site of an enzyme, altering the structure which will then alter its function
once the substrate is removed from the enzyme what happens to the enzyme?
It will then return to its normal & original design/function
what can prevent substrate binding?
a competitive inhibitor
how does a competitive inhibitor function?
the competitive inhibitor will bind to the active site of an enzyme, preventing the substrate from binding
