- What is phosphorylation?
What are some biological
processes in which
phosphorylation plays a
critical role?
Phosphorylation processes of the addition ois the name given tof phosphates (^)
to some molecules thus making these
molecules moPhosphorylation re energized.has an important r (^) ole,
for example, in photosynthesis (the
photophosphorylation and in aerobic respiration (oxiof the light phase)dative
phosphorylation of the respiratory
chain). In general thphosphorylation come phosphate ues from ATP sed in
molecules.
- Why is iodine important
for human beings?
Iodine is a fundamental chemical
element for the proper functioninthe thyroid since it is part of the g of
hormones produced by this gland.Iodine deficiency creates a kind of (^)
hypothyroidism, a disease known as
endemic goiter.
- What are the main
biological functions in which
chlorine ions participate?
Like sodium cations, chlorine anions
activelythe osmolarity of participate in tissuesthe regulation o and cells by f
crossing the cellular membrane and
avoiding entrance of water or excessive loss of water from the cell.into the cell (^)
Chlorine anions have an important role
for the acid-base balance of the
organism since with bicarbonate aniothey participate, alonns, in the pH g
buffer system of the body. Another
function physiology: of chlorine inside the gastricis in the digestive lumen,
hydrochloric acid secreted by stomach
cells iochlorine ions lownizes itself into ering the pH of thehydrogen and
gastric juice and then permitting the
enzymatic digestion to take place.
