dehydration synthesis

A

taking out the water to dehydrate and synthesize to make a larger molecule

31
Q

Hydrolysis

A

Adding water so we can split a larger molecule apart into smaller molecules

32
Q

Do lipids dissolve in water?

A

Hydrophobic, don’t dissolve well in water, has lots of C, H; Few O

A

Triglyceride and Saturated and Unsaturated fats

36
Q

3 Functions of lipids

A
  1. secondary energy source
  2. formation of communications molecules - steroids and prostaglandins
  3. structural component like phospholipids we find in the plasma membrane.
37
Q

amphipathic and what molecule is a amphipathic

A

Phospholipid
Amphipathic - being both hydrophilic and hydrophobic

38
Q

what do amino acids form

A

Proteins

39
Q

What drives passive transport in cell membranes?

A

Concentration gradients

40
Q

Passive transport

A

Doesn’t use energy

41
Q

Active transport

A

Uses carrier protein, includes pumps, goes against gradient
