BSC 108 UA EXAM 2 QUESTIONS AND ANSWERSWhat inputs are required for photosynthesis to produce oxygen and glucose? -
answers-sunlight, carbon dioxide, water
How is aerobic respiration different from anaerobic respiration? - answers-aerobic
respiration requires the presence of oxygen while anaerobic does not require oxygen
What is the equation for aerobic cellular respiration - answers-glucose + oxygen ->
carbon dioxide + water + energy
What is the function of cellular respiration - answers-to breakdown sugar in the
presence of oxygen in order to release energy through atp
Equation for anaerobic respiration (fermentation) in yeast - answers-c6h12o6 ->
c6h12o6 -> 2ch3ch2oh + 2co2 + energy
What three factors affect the amount of co2 produced by fermentation - answers-1.
Temperature
2. Concentration of sugar
3. Concentration of yeast
Why do disaccharides produce more co2 than monosaccharides? - answers-
disaccharides are able to be broken down so they are able to produce twice as much
co2 than monosaccharides
What types of genetic information can and cannot be determined from a punnett
square? - answers-cannot predict the sex of the offspring, can predict certain
percentages of an offspring's genotypes and phenotypes.
T or f, a human is an autotroph - answers-false
Stomata - answers-a pore in a leaf
Stroma - answers-thick fluid inside a chloroplast
Photosystem - answers-light-harvesting unit in chloroplasts
Thylakoid - answers-disk-shaped sac in the stroma of a chloroplast; site of the light
reactions of photosynthesis
Autotroph - answers-an organism that makes its own food from inorganic ingredients
Photosynthesis contributes to plant growth by_______ - answers-taking in carbon
dioxide and making sugars
, Photosynthesis equation - answers-carbon dioxide + water + light energy -> glucose +
oxygen
What molecule is produced during the light reactions of photosynthesis - answers-o2 or
oxygen
The light reactions of photosynthesis take place_______ - answers-in the thylakoid
membrane
Processes of photosynthesis in the order of which they occur - answers-light absorption,
water splitting to produce oxygen, atp and nadph synthesis, carbon fixation, g3p
synthesis
What is the primary function of pigments in photosynthesis, what is the primary pigment
used in photosynthesis? - answers-to absorb light energy, chlorophyll
T or f, leaves are green because they absorb green wavelengths of light - answers-false
T or f, the two main stages of photosynthesis are the light reactions and the calvin cycle
- answers-true
What compound are a direct output of the calvin cycle? - answers-g3p; rubp
T or f; the products of the calvin cycle are glucose and oxygen - answers-false
The products of the light reactions include______ - answers-atp and nadph
Events of the calvin cycle - answers-fixation, reduction, and regeneration
What are the stages of mitosis? - answers-interphase, prophase, metaphase,
anaphase, telophase, cytokinesis
How does meiosis differ from mitosis? - answers-meiosis produces cells that are
genetically different. Mitosis produces cells that are genetically identical.
Mendel's first law - answers-the law of segregation; during gamete formation each
member of the allelic pair separates from the other member to form the genetic
constitution of the gamete
Mendel's second law - answers-law of independent assortment: alleles of different
genes assort independently during gamete formation
What is a monohybrid - answers-a hybrid that is heterozygous with respect to a
specified gene.
