Biology 1000 exam #2 Matthew Kearley Questions With
Complete Solutions
Are enzymes permanently altered in these chemical reactions?
Correct Answers no
ATP is created from an ATC (thylakoid membrane) NADP+ and
is reduced to become what? Correct Answers NADPH
C6H126O2 ----- Correct Answers 6CO2 + 6H20 + ATPs
catechol oxidase regulates a reaction in which catechol is broken
into benzoquinone. In this reaction is catechol the enzyme,
product or substrate? Correct Answers substrate
characteristics of Eukaryotes Correct Answers everything else,
nuclei, many are multicellular, most use oxygen and organelles
characteristics of Prokaryotes Correct Answers archaea or
bacteria, no nuclei, single-celled, many don't use oxygen and no
organelles
define chloroplasts Correct Answers they contain chlorophyll
and accessory pigments
define grana Correct Answers sack of thylakoids
define pigments Correct Answers molecules that absorbs
certain wavelengths of light and reflect/transmit others
, define stomata Correct Answers pores in the leaf that let carbon
dioxide in and water and oxygen out
define stroma Correct Answers fluid within the chloroplast and
surrounds the thylakoids
define thylakoid Correct Answers flattened membrane bound
sac in the interior of the chloroplast
does anaerobic respiration use oxygen? Correct Answers no
energy Correct Answers the ability to do work (bring about the
movement against an opposing force)
energy is often transformed into what Correct Answers heat
enzymes are highly specific and usually only catalyze how many
reactions? Correct Answers one
enzymes bind to the substrate making these molecules more
vulnerable to what? Correct Answers chemical alteration
extremely high temperatures do what to the enzyme? Correct
Answers it changes the shape and substrates can no longer bind
to the active site
H2CO3 is an acid. If we drop it into a neutral solution, then
what happens? Correct Answers the number of hydroxide ions
(OH-) will increase
