thermodynamics

Question 1

chemical reactions?

Answer 1

process that changes chemical substances. reactions interact and are used up to form products. numbers before molecules is how many there is.

Question 2

exergonic?

Answer 2

exothermic + catabolic, reaction releases energy.

Question 3

endergonic?

Answer 3

endothermic + anabolic, reaction captures energy.

Question 4

metabolism?

Answer 4

all catabolism and anabolism in an organism.

Question 5

enzyme?

Answer 5

the protein binds reactants and helps them –> products. always all body chemistry requires enzymes. different enzymes have different pH requirements.

Question 6

alleles?

Answer 6

for malfunctioning enzymes –> genetic disease.

Question 7

water?

Answer 7

electrophilic - O created polar bonds with H. partial charges poles attract anything electrically charged. hydrogen bonds provide cohesion. cohesion provides surface tension. cohesion gives high heat carrying capacity for liquid water.

Question 8

acids and bases?

Answer 8

fraction of H2O molecules split to hydronium and hydroxide. equal proportions equal a neutral solution. acids have a pH lower than 7, they contain more hydronium than hydroxide. bases or alkaline have more hydroxide than hydronium and have a pH greater than 7.
