What are the differences between receptor-mediated endocytosis and phagocytosis?

Receptor-mediated endocytosis uses special receptor proteins to help carry large particles across the cell membrane.

Phagocytosis engulfs large particles and brings them into the cell through vesicles. Those vesicles then merge with a lysosome to breakdown the material within the vesicle.

Explanation:

dna is made up of six smaller molecules -- a five carbon sugar called deoxyribose, a phosphate molecule and four different nitrogenous bases (adenine, thymine, cytosine and guanine).

a motor homunculus represents a map of brain areas dedicated to motor processing for different anatomical divisions of the body.

homunculus represents the importance of various parts of your body as seen by your brain. as a result, they take up a lot of brain space. although the cortical homunculus is a curiosity, penfield's work in mapping the brain's relationship to the body was invaluable.
