Answer:
Ligand A and ligand B can cause same cellular responses in a cell when they are attached to different receptors.
Explanation:
If two same ligands are attached to two different receptors, two different responses will occurs. Such type of response is present in acetylcholine, while when two different ligands attached to two different receptors, same response will occur. This type of response is present in glucagon and epinephrine etc. ligands are responsible for controlling the transcription process when it binds or attached to the DNA molecule of the cell.
Answer:
option A
Explanation:
ornithine is a non-protein and non-essential amino acid it is formed in plant by L-glutamate and in animals it is formed during the urea cycle by the catalyzation of arginine which is an enzyme. In vivo ornithine is not found in protein synthesis because it do not have any codon so it can not endoded by DNA but can be synthesized.
Ornithine is a precursor of glutamic acid, proline amino acid and citrulline amino acid
Answer:
It saves time
Explanation:
You don't have to draw unnecessary details for complex structures
Answer:
The experimenter hypothesized that fertilizer would make the plants grow taller. The results show that, on average, plants with fertilizer grew 0.7 cm taller over the course of 12 days. This small amount of height increase could be attributed to the fertilizer or may be caused by natural differences in the plants.
Explanation:
A few enzymes<span> exhibit absolute </span>specificity<span>; that is, they will catalyze only one particular reaction. Other </span>enzymes<span> will be specific for a particular type of chemical bond or functional group. In general, there are four distinct types of </span>specificity<span>: Absolute </span>specificity<span> - the </span>enzyme<span> will catalyze only one reaction.</span>
