Question

what is facilitated diffusion? movement of substances against a concentration gradient movement of substances using energy movement of substances down a concentration gradient with the help of transport proteins movement of water across a membrane question 13 0.75 pts which process involves the engulfing of large particles by the cell membrane? osmosis diffusion exocytosis endocytosis

Explanation:

Brief Explanations

Facilitated diffusion is a passive - transport process where substances move from an area of higher concentration to an area of lower concentration (down a concentration gradient) with the help of transport proteins (channel or carrier proteins). Endocytosis is the process by which the cell membrane engulfs large particles or substances. Osmosis is the movement of water across a semi - permeable membrane, diffusion is the movement of substances from high to low concentration without the need for transport proteins, and exocytosis is the process of releasing substances out of the cell.

Answer:

For the first question: Movement of substances down a concentration gradient with the help of transport proteins
For the second question: Endocytosis
