Answer:
a. A significant decrease in potential energy occurs as the charge repulsion diminishes
Explanation:
Adenosine triphosphate, or ATP, is a relatively simple small molecule. It serves as the main energy currency for cells, similar to how money functions as the primary currency in human economies. The energy released during the hydrolysis (breakdown) of ATP is harnessed to facilitate numerous cellular processes that require energy.
Phosphoanhydride bonds are deemed to be high energy, due to the considerable drop in potential energy when charge repulsion is lessened.In fact, this means that a substantial amount of energy is liberated when one of these bonds is cleaved in a hydrolysis reaction, which involves the interaction with water. The reaction converting ATP into ADP is represented as follows:
ATP + H2O ⇄ ADP + Pi + energy
where Pi signifies an inorganic phosphate group
Like many chemical reactions, the hydrolysis of ATP into ADP can be reversed. Regeneration of ATP from ADP and Pi needs energy input. This regeneration is crucial since cells rapidly utilize (hydrolyze) ATP molecules and require their constant replenishment.
Answer:
B) Lysosome
Explanation:
Lysosomes are organelles within eukaryotic cells, characterized by a covering of double membranes and an internal composition of hydrolytic enzymes. These enzymes, commonly referred to as digestive enzymes, play important roles in catalyzing the breakdown of proteins and various complex molecules. Examples of hydrolytic enzymes located within lysosomes include proteases, glycosidases, and phosphatases.
The crossing over of homologous chromosomes occurs in meiosis.
The nurse must take steps to limit the amount the child absorbs into their system. Additionally, the nurse should promote the elimination of any toxins ingested by the child while providing necessary supportive care.
