Caffeine prolongs and intensifies the effects of epinephrine. Which of the following potential mechanisms of action of caffeine
kherson [118]

Answer:

a. inhibits cAMP phosphodiesterase, the enzyme that converts cAMP to AMP.

Explanation:

The phosphodiesterases are a group of enzymes that are capable of breaking phosphodiester bonds such as those between nucleotides in nucleic acids. The Cyclic adenosine monophosphate (cAMP) is a second messenger involved in intracellular signaling pathways. This molecule (cAMP) is hydrolyzed by the cAMP-dependent phosphodiesterase, which catalyzes the enzymatic breakdown of phosphodiester bonds (i.e., hydrolyzing cAMP to 5-AMP). The cAMP levels are modulated by the balance between its generation and the degradation via cyclic nucleotide phosphodiesterase.

____ [38]

Answer:

The % of children with webbed digits is 50%

Explanation:

Given -

Syndactyly or webbed digits are due to the presence of  a dominant allele (S). Then the allele for normal digits would be represented by allele "s"

A normal man with normal digits and genotype "ss" marries a woman with webbed digits and has a hetrozygous genotype i.e "Ss"

If we cross Ss and ss , then the following offspring are produced -

Ss * ss

Ss, Ss, ss, ss

Out of four 2 offspring with genotype ss have normal digits and remaining two offspring with genotype "Ss" have webbed digits. Thus, the % of children with webbed digits is 50%
