I have two amino acid sequences from a protein that appear to be associating with each other. The sequences are LTLDVA and VQLEIV.
What might you consider for these sequences as far as secondary structure?

a. Turn
b. Helix
c. Beta sheet
d. Cannot predict

The correct answer is option C.

Explanation:

The amino acids sequences that are present in two proteins that are seems to  be associated with one other, the sequences are LTLDVA and VQLEIV residues.

These residues such as tyrosine, tryptophan. phenylalanine, theronine, valine, isoleucine are found in beta sheets favorably, in the given sequences val and Thr is rich in beta sheets.

Thus, the correct answer is -option C.

it's c. (to reduce the greenhouse effect/carbon gasses)

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
