2. regulates processes
3. makes up enzymes
2 functions for carbohydrates
1. provides all energy needed for life
2. functions as food reserves
3. make structures DNA/RNA
give lipid group approp eg or function of:
1. adipose tissue
2. progesterone and aldosterone
3. this group of lipids is inhibited by aspirin
4. this group of lipids forms plasma membranes
1. triglycerides
2. steroids
3. eicosanoids
4. phospholipids
nucleotides are joined together by __________ bonds
phosphodiester
fatty acids with the maximum number of hydrogen attached are known as _______ fatty acids
saturated
2 characteristics of enzymes that make them so important to organisms
1. highly specific
2. cellular controls
3. extremely efficient
how is water having high heat of vaporization important to life
allow body to cool itself during prespiration
Why do extremes in pH or temp affect the body? How are chaperonins involved?
Extremes in pH levels make the body either more acidic or basic effecting the body's homeostasis and causing protein denaturing. Chaperonins help renature proteins.
