What is the major difference in the production of transgenic bacteria, plants, and animals?
Flauer [41]

Answer:

Transgenic animals require a host to grow but transgenic bacteria and plants do not require host.

Explanation:

Transgenic organisms are the organisms in which foreign genetic material are introduced so that the transgenic organism can get some particular traits and characteristic.

The process of producing transgenic animals is different from producing transgenic plant and transgenic animals because in transgenic animals DNA from a cell is transferred into an enucleated oocyte.  

Then this oocyte is transferred to the oviduct of a surrogate mother to raise the genetically modifies embryo but in plant and microbe, no host is required.

A cell pumps hormones out into the bloodstream; a process that requires energy. If 4 ATP were converted to ADP, how much energy
dedylja [7]

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.
