Glucose Catabolism
1) Aerobic cellular respiration
Glycolysis, Citric Acid cycle, Electron Transport Chain etc.
2) Anaerobic Respiration
3) Fermentation
Name the three major pathways for glucose catabolism (on the top ^) and briefly describe them (names of major step, inputs, outputs). For inputs and outputs, consider both carbon-based molecules and energy-containing molecules.
For each pathway, discuss:
An example of a final electron acceptors for each pathway
The relative electronegativity of the final electron acceptor (comparing the 3 pathways)
Relative amount of ATP made
Whether the pathway is complete or incomplete oxidation
Whether the pathway is aerobic or anaerobic
Thank you in advance :)

Match each scenario with the type or mode of selection that fits best. Answers can be used more than once. Group of answer choices
1.A population of Madagascar hissing cockroaches lives in a woodpile. It suffers heavy predation from lizards. Because their heads are small, the lizards are unable to eat the very largest adult cockroaches, and instead prey upon small and medium sized adults. What type of selection do the lizards impose on the roaches?
2.Indian paintbrush flowers vary from dark to light red in color. Bumblebees form a search image for flowers that have medium (average) red coloration, and preferentially pollinate those flowers.
3.A beetle species is introduced to an island covered with dark basaltic rock. The beetles range in coloration from dark brown to a very light brown. On this dark background, darker beetles are much more resistant to predation than are lighter-colored beetle. The dark beetles have a large selective advantage. All phenotype are relatively common in the group of beetles released on the new island.
4.In a species of bird, individuals with genotype MM are susceptible to avian malaria, Mm birds are resistant to avian malaria, and the mm birds are resistant to avian malaria, but the mm birds are also vulnerable to avian pox.

1. (a) How do Chaperones prevent aggregation?
(b) Is the existence of chaperons, and their necessity in many cases, consistent with the idea that ALL of the folding information for proteins is in the primary sequence?
(c) Reconcile (or refute) the fact that chaperonins require ATP energy for their activity with the statement that proteins "self-assemble".

Certain antibody isotypes are more important from blood-borne infections while other isotypes are more important for food-borne infections. Taking this into consideration, draw two different immunoglobulin with different effector functions, present in two different tissues of the body. Your drawing should demonstrate the effect the specific antibody isotype has within the tissue.
Include:
1) labels to indicate the isotype of the antibody you have drawn
2) labels to indicate the receptor that recognizes the antibody, the cell with the receptor, the tissue which the cell is located in, an antigen binding to the antibody, and the effect the antibody performs.
3) add a sentence or two to describe what happens to a person lacking the certain receptor or antibody you have described in each drawing.

Fruit flies, like all insects, are covered with fine, hair-like bristles, which serve as sensory structures.
You discover a male fruit fly, which has short, under-developed bristles.
You cross this male fly with a female fly with normal bristles. Of 400 progeny, you count 205 flies with normal bristles and 195 with short bristles. You cross two F1 flies (both have short bristles) and count 400 progeny; 267 have short bristles and 133 have normal bristles.
A test cross of the F1 short bristle flies results in the following results: 195 flies with short bristles and 205 flies with normal bristles.
A reciprocal cross (short-bristled female flies with normal males) yields similar results in the F2.
A. Do what of inheritance pattern do you think this trait is showing ?
B. What conclusions can you make about the allele causing short bristles and the genotype of the original male?
C. What is the best explanation for this phenotypic pattern?
I chose
A. Homozygous dominant lethality
B. dominant
C. Individuals with the genotype BB and Bb show SHORT bristles, and those with bb show NORMAL bristles
But I got 4/6 points, not sure which I got wrong.
