two enzymes, e1 and e2, are both able to catalyze the same chemical reaction. if km1 (for e1) is larger than km2 (for e2), which enzyme has a higher affinity for the substrate?

Answers

1. Because Km is inversely related to affinity, E2 has a high affinity for substrate.

E1 has a higher Km value and a lower affinity. E2 has a low Km and a strong affinity.

.High-affinity enzyme ligands are substantially bigger than low-affinity ligands, indicating that the addition of complementary functional groups is likely to boost an enzyme inhibitor's affinity.

Elderly people are more likely to develop hypernatremia. These patients frequently have acid-base imbalances, a reduced glomerular filtration rate, and decreased blood supply to the kidneys. Kidney and bladder difficulties, such as urinary retention, leakage, or urinary incontinence (inability to contain pee), are more likely to develop as we age, including UTIs of the bladder and other types.

Answers

A generating potential is the first reaction that occurs when odorant molecules come into contact with the dendritic processes of olfactory receptors. Here option C is the correct answer.

The cilia of the olfactory sensory neurons are where olfactory transduction occurs. G protein called Golf is activated when odorant molecules connect to odor receptors (R) in the ciliary membrane. This G protein then activates adenylyl cyclase (AC), increasing the production of cAMP from ATP.

Each receptor cell contains a single external process that extends to the epithelium's surface and produces a number of cilia, which are long, thin projections. The nasal cavity's mucus covers the cilia, making it easier for olfactory receptors to detect and react to odor molecules.
