What conditions do most enzymes work best at?
Give this one a try later!
, for humans:
temperature: 35-40°C (95-104°F)
pH: neutral (6-8)
EXCEPTIONS TO BOTH
Besides passing electrons to each other through an electron transport chain, what
else do these proteins do? (Follow green arrows).
Give this one a try later!
use energy released from electron transfers to actively transport H+ across
the membrane, from lass concentrated to more concentrated
What are the distinctions between phagocytosis and receptor-mediated endocytosis?
Give this one a try later!
phagocytosis: plasma membrane eats large molecules by wrapping
extensions around called pseudopodia and puts them in membrane-
enclosed sac called a vacuole; vacuole fuses with lysosome and uses
hydraulic enzymes to digest particles
receptor-mediated endocytosis: receptor proteins for specific molecules
are embedded in regions of the membrane that are lined by a layer of coat
proteins; plasma membrane indents to form a coated pit, whose receptor
proteins pick up particular molecules from extracellular fluid; coated pit
pinches closed to form a vesicle, which then releases into the cytoplasm
What is the main function of fats?

, long term energy storage
Compare and contrast eukaryotic and prokaryotic cells:
Give this one a try later!
eukaryotic: membrane around DNA (nucleus), cell wall only in plants
both: DNA, ribosomes, plasma membrane
prokaryotic: no nucleus, smaller ribosomes, cell wall, flagella
What are the three major categories of sex hormones?
Give this one a try later!
estrogen, progestins, and androgens
How is a theory different from a hypothesis?
Give this one a try later!
theory is much broader in scope and is supported by a large and usually
growing body of evidence
When water moves through a selectively permeable membrane down its
concentration gradient this is termed ______________.

List the molecular bond types:
Give this one a try later!
1. covalent bond- share electrons (1, 2, or 3 pairs); can be VERY strong.
2. ionic bond- electrons are not shared ( EX. NaCl [table salt]- Cl takes Na's
valence electron to complete 3rd shell which makes both of them ions,
earning charges)
3. hydrogen bond- attraction between a slightly positive hydrogen (from a
polar molecule) and a slightly negative atom (from a different polar
molecule) (weak, easily broken with heat)
