Answer:
Recombinant DNA
Explanation:
Recombinant DNA can be used to change the genetic makeup of a cell, as in adding a gene to make a bacterial cell produce insulin.
The answer is an attraction between polar molecules
Answer: C). prolong the effect of epinephrine by maintaining elevated cAMP levels in the cytoplasm
Explanation: In the epinephrine pathway, binding of epinephrine to its receptor triggers a conformational change in the receptor and the interaction of the receptor with its associated Gs protein. This interaction causes the replacement of GDP bound to Gs protein with GTP thus activating the Gs protein. The activation of the Gs protein causes the alpha subunit of the Gs protein to dissociate and move to adenylyl cyclase, another membrane protein in the pathway. The association of the alpha subunit of the Gs protein with adenylyl cyclase activates adenylyl cyclase which in turn catalyzes the synthesis of cyclic AMP (cAMP) a second messenger. cAMP is quickly degraded to 5'-AMP by an enzyme phosphodiesterase. Inhibition of the activity of phosphodiesterase will increase the half life and the cytoplasmic level of cAMP thus potentiating the action of epinephrine.
Answer:
D, over the past Billions of years, our atmosphere has formed to protect life.
It is 122KJ of energy is used from the conversion of ATP to ADP because hydrolyses of 1 mole of ATP requires 30.5KJ of energy. Therefore, if 4 ATP is hydrolyses, it will be 4× 30.5=122KJ. ... This energy is given out because there is cleavage of high energy phosphate bond in ATP while converting it into ADP.
