Biology 1320 Exam 2 Joel Bergh
What is an Okazaki fragment? - short sections of DNA
What is complementary base pairing? What is the complement of 5'-CGCATGTCAGC-3'? -
GCGTACAGTCG
What is the structure and function of the different parts of the leaf (mesophyll and stomata)? -
Mesophyll is the green material of a leaf that allows the plant to enact the process of
photosynthesis.
stomata is the openings or pores in the leafs that allow for gas exchange
Know the chemical equation for photosynthesis. - 6CO2 + 6H2O + sunlight energy = C6H12O6 +
6O2
What are the different parts of the chloroplast and where do the different steps of photosynthesis take
place? - Thylakoid: one of the green discs.
Granum: stack of thylakoids
lumen: the shit inside the thylakoid
stroma: the aqueous fluid
Photosynthesis takes place inside plant cells in small things called chloroplasts.
What is the reactants that go into the light reaction and what products are created? - Reactants:
Light, H20
products: ATP, NADPH
What are the reactants for the light independent reaction, where do they come from, and what are the
products of the Calvin cycle? - occurs in stroma.
reactants: NADPH, ATP, and C02
products: glucose
Know that ATP and NADPH are energy carrier molecules. -
What is the role of chlorophyll a and the accessory pigments in the light reaction? - chlorophyll a
is the primary photosynthetic pigment in plants. it absorbs mostly blue and red light.
How do we measure the intensity of light? Which is stronger, red light or blue light and why? - in
wavelengths. blue light because it has shorter wavelengths.
, Understand the role of chlorophyll in photosynthesis? What light does chlorophyll absorb or reflect? -
chlorophyll a absorbs blue light, chlorophyll b absorbs red light, both reflect green light which
causes chlorophyll to be green
Know the chemical equation for complete glucose breakdown (glycolysis and cellular respiration) and
how this relates to photosynthesis. - 602 + C6H12O6 -> 6C02 + 6H20 + energy (ATP)
Where in the mitochondria does glycolysis occur? What about cell respiration or fermentation? -
glycolysis occurs in the cytoplasm.
Fermentation only generates ATP in glycolysis
What does glycolysis stand for and what are the reactants and major products that are produced the
reaction? - glycolysis stands for the breaking of glucose. reactants are glucose (c6h12o6) and the
products is 2atp & 2nadh molecules, and 2 pyruvates.
What are the initial reactants and products for the transition of pyruvate into acetyl-CoA, Krebs cycle,
the electron transport chain, and fermentation (both pathways of fermentation that result in either
alcohol or lactic acid). - glucose is broken down by glycolysis to form 2 pyruvates which turn into
acetyl-coa which then with aerobic oxygen goes into the krebs cycle then to electron transport chain
producing a shit load of ATP. otherwise w/o oxygen, it is led to fermentation which for humans results in
built up lactic acid, or yeast cells for alcohol fermentation
At what steps is CO2 produced and what happens to the gas? - Acetol COA produces CO2 as well
as the The Krebs cycle produces CO2. the gasses are used in the electron transport chain to produce atp.
What happens to cellular respiration if no oxygen is present? Why does the mitochondria enter
fermentation when there is no oxygen present? - if no oxygen is present then fermentation occurs
which can build up alcohol fermentation with yeast or lactic acid in humans. can only produce a net of
2atp's.
What happens to cellular respiration if FADH2 or NADH cannot give up their hydrogens? -
fermentation happens
How much ATP is produced during glycolysis, Krebs, the electron transport chain, and fermentation? -
glycolysis : 2 ATP's
Krebs: 2 ATP's
Electron Transport chain: 34ATPS's
fermentation: 2ATPs
What is the difference between aerobic and anaerobic respiration? - aerobic respiration is with
oxygen, anaerobic respiration is without oxygen.
What are the four nucleotides found in DNA and how do they pair up with each other. - Adenine,
Thymine, Cytosine, & Guanine. Adenine pairs with Thymine while Cytosine pairs with Guanine
