|
T or F: The more unsaturated the fatty acid is, the lower it's melting point? |
True |
|
|
What is facilitated diffusion? |
Something that helps a molecule across a membrane. It is a passive process. |
|
|
What is primary active transport? |
Uses energy directly when transferring something across a membrane. |
|
|
What is secondary active transport? |
The molecule is moved by a gradient difference |

|
Glycogen phosphorylase degrades glycogen and must be phosphorylated to be active Glycogen synthase synthesizes glycogen and is inactive when phosphorylated. How do insulin and glucagon regulate these |
Glucagon triggers phosphorylation so it increases degradation and decreases synthesis Insulin triggers the activation of phosphatases that remove phosphates turning synthesis on and degradation off, reversing the effect if glucagon |
|
|
Gel filtration separates by what |
Separates by weight. The heavier stuff will come out first |
|
|
How does an anion exchange colum separate out stuff if the pH is 7.4 |
Those with a pI lower than the pH will be filtered out first, than as increasing pH |
|
|
