When adrenaline binds to adrenergic receptors on the surface of a muscle cell, it activates a G protein, initiating an intracellular signaling pathway in which the activated α subunit activates adenylyl cyclase, thereby increasing cAMP levels in the cell. The cAMP molecules then activate a cAMP-dependent kinase (PKA) that, in turn, activates enzymes that result in the breakdown of muscle glycogen, thus lowering glycogen levels. You obtain muscle cells that are defective in various components of the signaling pathway. Referring to Figure Q16-29, indicate how glycogen levels would be affected in the presence of adrenaline in P the following cells. Would they be higher or lower than in normal cells treated with adrenaline?
A. cells that lack adenylyl cyclase higher
B. cells that lack the GPCR higher
C. cells that lack cAMP phosphodiesterase lower
D. cells that have an α subunit that cannot hydrolyze GTP but can interact properly with the β and γ subunits lower
If a plant that is 4n undergoes sympatric speciation by autopolyploidy, what will be its ploidy as a new species?
There they discover his mitochondria can use only fatty acids and amino acids for respiration, and his cells produce more lactate than normal. Of the following, which is the best description of his condition.
Consider the following segment of double-stranded DNA, which is part of a much longer molecule constituting a chromosome. This sequence is located ~2000bp to the left of its origin of replication.
Why is understanding the structure and function of self-replicatingmolecules (i.e. RNA) essential to hypotheses about the origin oflife?
During cell division, organelles such as the ER and mitochondria are distributed intact to each daughter cell. These organelles contain information that is required for their construction, and so they cannot be made de novo.
Karyotypes are used in a clinical situation to determine the presence of certain genetic diseases. Often they are performedusing the amniotic fluid of the pregnant mother. Write a briefparagraph explaining the what, how and why of karyoptypes.
