Answer:
C if you plug it into the sentance its the only one that makes sense
This would be true, yes!
Goodluck :-)
Answer:
Glycogen phosphorylase kinase (GPK) that plays an important role in glycogenolysis. The enzyme release the glucose 1- phosphate from the alpha-1,4-glycosidic bond.
The alpha and beta subunit of cell line A get changed. GPK activates in case when the phosphorylation is removed or Ca2+-Calmodulin is eliminated. A cell line has reversed the Ca2+•Calmodulin activity dependent on GPK. This cell line only requires the calcium level back into cytosol. The cell line B PKA ( protein kinase A) activation that are dependent on GPK is slowoly reversed in the absence of the calcium ion beacuse protein dehydrogenase 1 (PDK) is not get activated. This causes the fall in cAMP level slowly and allow the longer persistence of the PKA activity & GPK phosphorylation.
Thus, the answer is In cell line "A" certain S or Ts on the α+ β subunits of GPK were changed to A. In cell line "B"; the ER Ca2+ channels could not bind IP3.
phoresy - a relationship between two or more organisms of different
species in which one benefits and the other is harmed
monogamy - having one mate for a whole life span
mutualism - a symbiotic relationship between two organisms in which
both species receive some type of benefit
polyandry - when females mate with multiple males
polygyny - when males mate with multiple females
parasitism - a relationship between two or more organisms of different
species in which one benefits and the other is harmed

Symbiosis</h2>
Symbiosis is the name given to any close and long-term interaction between two different species.
This interaction can be beneficial to one part only and harmful to the other (parasitism), it can be beneficial to all parts (mutualism), or it can benefit one part without influencing neither positively nor negatively the other (commensalism).
A mating system refers to how a group is organized in terms of sexual behavior. When it comes to animals, the phrase refers to which males and females mate when certain conditions are met. Monogamy, polygamy (including polygyny, polyandry, and polygynandry), and promiscuity are all recognized systems that lead to various mate choice outcomes and so influence how sexual selection operates in the species that practice them.
