Answer:D

Explanation:

Respiration is the process of taking in oxygen and release of Carbondioxide in the lungs(breathing),the absorption of the oxygen in the alveolar, into the blood stream for distribution to tissues , the combustion of the metabolites(glucose,amino acids, and fatty acids and glycerol)with the inhaled oxygen to give energy as ATPS and water vapour.

Fudgin [204]

Answer:

This is because fluids have a polar nature, so they couldn´t cross the lipidic bilayer that constitutes the plasma membrane

Explanation:

Plasma membranes are contituted by lipid bilayers. These kind of compounds are hidrophobic (they reject water) and don´t permit the freely passage of hidriphilic molecules that can disolve in water, constituing fluids. Because of that cells developed transport mechanism like endocytosis.

GrogVix [38]

Answer:

"GFP contained in synaptic vesicles moved into the synaptic cleft by exocytosis."

Explanation:

Synaptic vesicles are small membrane sacs that carry neurotransmitters from the cell body where they are produced, to the presynaptic membrane of the terminal button where they are released. The release zone of the presynaptic membrane contains voltage-dependent calcium channels. When an action potential depolarizes the presynaptic plasma membrane, Ca^{2+}-channels open, and  Ca^{2+} flows into the nerve terminal to trigger the exocytosis of synaptic vesicles, thereby releasing their neurotransmitters into the synaptic cleft

stellarik [79]

Answer:

Native conformation

Explanation:

Native conformation is the correct structure or shape a protein should assume when folded, of which the protein is able to perform its operational function. Outside a proteins native conformation, or when denatured, the protein becomes unable to perform its usual main functions. The native conformation of a protein is the shape it takes in other to be functional.
