Genetics
In fruit flies (Drosophila), vestigial wings (v) are recessive to normal wings (V).
What phenotype(s) of offspring would you expect from the following cross, Vv x vv?
Two vestigial and two normal wings
Photosynthesis takes place in the membranes of small sacs called
Thylakoids
An organism cannot survive without catabolic pathways because
energy would never be released from complex molecules
In mitosis, two sister chromatids are attached at this position
Centromere
The pumps that move Na+/K+, H+/K+, and Ca2+ of skeletal muscle across cell membranes are examples of
Active Transport
Two plants are mated and 250 offspring are phenotypically classified.
61 plants display the recessive phenotype and, 189 plants display the dominant phenotype.
Assuming classical Mendelian patterns of inheritance, what are the most likely genotypes of the parent plants?
Heterozygous & Heterozygous
Both Carotenoids and Chlorophyll are known as:
Pigments
This is the location where glycolysis takes place
Cytoplasm
During prophase I, crossing over is responsible for:
Contribute to Genetic Diversity
Amphipathic molecules have the following:

Chromosome mapping shows that genes F and G are 60 map units apart.
genes F and H are 20 map units apart
genes H and G are 40 units apart.
What is the sequence of these 3 genes on this chromosome?

Colors of light most useful in photosynthesis are:
Red, Blue & Violet
What is true of aerobic respiration but NOT of anaerobic respiration?
A) 2 ATP are required for activation.
B) A chemiosmotic gradient is established.
C) Glycolysis is the primary process.
D) Proteins are metabolized.
E) Reduction-oxidation reactions occur.
B) A chemiosmotic gradient is established.
One major difference in Meiotic interphase that differs from mitotic interphase in that:
DNA Synthesis does not occur
Which of the following can diffuse through cell membranes?
A) Hydroxide ions and glucose
B) Methionine and hydrogen ions
C) Oxygen and vitamin D
D) Ribose and valine
E) Water and ammonium
C) Oxygen & Vitamin D
If Individual 9 marries a woman with one recessive allele, what are their chances of having a normal daughter?
25%
Production of one molecule of 3-Phosphoglyceraldehyde (PGAL) requires how many turns of the Calvin Cycle?
3 turns
During which stages of respiration are electron carriers reduced and oxidized, respectively?
Kreb's cycle & Electron Tranport Chain (ETC)
During mitosis, what would be the result if the microtubules failed to depolymerize?
Microtubules will NEVER shorten
In a plasma membrane, what event directly follows GTP binding to the G-protein-linked receptor?
G protein is activated
In pea plant pod shape can be swollen or pinched and the seed color can be either green or yellow. A plant with swollen yellow is crossed with a pinched green one and after self crossing we have the following data:
• 360 swollen yellow, • 120 swollen green, • 120 pinched yellow • 40 pinched green. •
Test the observation by doing the Chi-square test and decide your conclusion.
LESS THAN 7.82
ACCEPT NULL HYPOTHESIS
To reduce six molecules of carbon dioxide to glucose via photosynthesis, how many molecules of NADPH and ATP are required
12 NADPH & 18 ATP
In anaerobic respiration, ATP is formed through this process:
Substrate-level phosphorylation
What would happen if a cell was inhibited during the S phase of its cycle?
There will be a lack of DNA synthesis
Which of the following statements is true?
A) When signal molecules first bind to receptor tyrosine kinases, the receptors phosphorylate a number of nearby molecules
B) In response to some G-protein-mediated signals, a special type of lipid molecule associated with the plasma membrane is cleaved to form IP3 and calcium
C) In most cases, signal molecules interact with the cell at the plasma membrane and then enter the cell and eventually the nucleus
D) Toxins such as those that cause botulism and cholera interfere with the ability of activated G proteins to hydrolyze GTP to GDP, resulting in phosphodiesterase activity in the absence of an appropriate signal molecule.
E) Protein kinase A activation is one possible result of signal molecules binding to G protein-linked receptors
E) Protein Kinase A activation is one possible result of signal molecules binding to G protein-linked receptors
