Answer:
Active transport requires energy from ATP while facilitated diffusion does not
Explanation:
Active transport and facilitated diffusion with the use of channel and carrier proteins are both ways by which ions, polar and large molecules cross a selectively permeable membrane.
The major difference is that; Active transport transport these particles from a low to high concentration, which is against concentration gradient and hence, energy is required to perform the task
Facilitated diffusion transport from a high to low concentration, which is through a concentration gradient and hence, no energy is required to perform the task.
The answer is (A) evaporation, because when water gets hot it turns into a gas and rises into the air.
Answer:
Golgi receives a vesicle containing newly synthesized proteins that were sent by the endoplasmatic reticulum. Then it modifies the proteins and sends them where they need to go.
Explanation:
Protein synthesis is initiated in the cytoplasm when mRNA meets a free ribosome, which is the primary structure for protein synthesis. They read the mRNA code and add the correct amino acid using transference RNA to build the protein. The synthesizing protein is driven to the rough endoplasmic reticulum and translocated to the lumen. Once there, the protein suffers a few modifications, one of them is folding to become functional. Once membrane proteins are folded in the interior of the endoplasmic reticulum, they are <u>packaged into vesicles</u> and <u>sent to the Golgi complex</u>, where it occurs the <em>final association of carbohydrates with proteins</em>. The Golgi complex <u>sends proteins to their different destinies</u>. Proteins destined to a certain place are packaged all together in the same vesicle and sent to the target organ. In the case of membrane proteins, they are packaged in vesicles and sent to the cell membrane where they get incrusted.
