Answer:
Triglycerides
Explanation:
Fat cells are also called Adipose cells. They are cells found all over the body and majorly functions in the storage of energy storing substances called TRIGLYCERIDES. Triglycerides are a type of lipids composed of a glycerol molecule and three fatty acids molecules.
Triglycerides, like every other lipid, are biomolecules that store a large amount of energy. However, they are stored in specialized cells called FAT OR ADIPOSE CELLS.
Ethonal is produced during b. Alcohol fermentation that converst sugars into ethanol.
Answer:
<u>d. Transport proteins within the membrane serve as a tunnel for molecules to enter the cell.

Explanation:
Solutes are typically moved across the cell through either passive or active transport. The cells, surrounded by a bilipid layer or plasma membrane is amphiphlic- its polar, hydrophilic lipid heads face outwards, while their non-polar hydrophobic lipid tails face inwards towards each other.
While lipid-soluble molecules move across the layer easily, it is also difficult for charged and also large molecules to move across its surface, into the cell. Transmembrane channels, <u>embedded within the membrane</u>, help to maintain selective permeability as transport proteins, pores and gated channels. Simple diffusion happens as a method of passive transport in cells through plasma membranes.
The solutes travel through the plasma membrane in the process of diffusion from regions of high concentration to regions of low concentration; this occurs without the use of energy. <u>Molecules moving against their concentration require active transport mechanism to cross the membrane</u>.
SE LE CONOCE COMO IRRITABILIDAD
Los seres vivos tienen la capacidad de responder a una variedad de estímulos tanto del medio exterior como del medio interno. Esta capacidad de respuesta se denomina irritabilidad, porque es diferente a otro tipo de respuestas que se observan en la naturaleza.
