A cell pumps hormones out into the bloodstream; a process that requires energy. If 4 ATP were converted to ADP, how much energy was used? A. 4 kJ
B. 30.5 kJ
C. 122 kJ
D. 1600 kJ

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.

one is through turgidity. this occurs before ground tissue ( collenchyma

and sclerenchyma cells) become well

developed to give structural support to the plant as it grows bigger. the xylem

tissue (composed of rigid tissue) of the young

plant render this support and also maintaining osmotic turgidity of the surrounding

plant cells.

affects the water bodies: excessive use of fertilizers causes eutrophication. the fertilizers which are used on plants affect the quality of land on which it is used, further causing erosion of soil. the fertilizers used on plants contain harmful chemical fumes which affect the environment.
