What process allows movement of molecules that are too large to pass through a call membrane?
The process that allows movement of large molecules across a cell membrane is called endocytosis. In this process, the cell membrane engulfs the large molecules, forming a vesicle that brings them into the cell. There are different types of endocytosis, including phagocytosis for solid particles and pinocytosis for liquids. This mechanism enables cells to intake substances that cannot directly pass through the lipid bilayer of the membrane.

The process by which glucose can pass through a cell membrane by combining with special carrier molecules is called?
The process by which glucose can pass through a cell membrane by combining with special carrier molecules is called facilitated diffusion. In this process, carrier proteins aid in the movement of glucose across the membrane down its concentration gradient.
Which process would be describe the movement of sugar molecules through membrane from a region of higher concentration to a region of lower concentration?
This process is called passive transport or facilitated diffusion, where sugar molecules move down their concentration gradient without requiring energy input from the cell. Proteins in the membrane facilitate the movement of sugar molecules across the membrane.
Movement of water molecules across the membrane is the result of?
Movement of water molecules across the membrane is primarily driven by osmosis, which is the diffusion of water from an area of higher concentration to an area of lower concentration. This process occurs through specialized water channels called aquaporins that allow water to pass through the lipid bilayer of the membrane.
What is the movement of water molecules through a sectively-permeable cell membrane?
osmosis
What is the process called when molecules must join with another molecule such as a protein to get through a membrane?
The process is called facilitated diffusion. It is a type of passive transport that involves the movement of molecules across a membrane with the help of specific proteins called carrier proteins or channel proteins. These proteins assist the molecules in crossing the membrane by providing a pathway.

What is the movement of molecules through a membrane due to the pressure of a liquid on that membrane?
Osmosis.
What process do water molecules cross the cell membrane?
Water molecules cross the cell membrane through a process called osmosis, which is driven by the concentration gradient of water inside and outside the cell. Aquaporin proteins on the cell membrane facilitate the movement of water molecules into and out of the cell.

This process is called passive transport or facilitated diffusion, where sugar molecules move down their concentration gradient without requiring energy input from the cell. Proteins in the membrane facilitate the movement of sugar molecules across the membrane.
How does diffusion occur through a semipermeable membrane?
Diffusion through a semipermeable membrane occurs when molecules move from an area of high concentration to an area of low concentration, passing through the membrane. This process is driven by the natural tendency of molecules to spread out and reach equilibrium. The semipermeable membrane allows only certain molecules to pass through based on their size and charge, regulating the movement of substances across the membrane.

Diffusion
What is the movement of water through diffusion called?
The movement of water through diffusion is called osmosis. Osmosis is the process where water molecules move from an area of higher concentration to an area of lower concentration across a semipermeable membrane.

What is the name of the membrane that allows the movement of water and substances to move through the process of active transport and passive transport?
The cell membrane, also known as the plasma membrane, is responsible for regulating the movement of water and substances through processes like active transport and passive transport. It acts as a selectively permeable barrier, allowing certain molecules to pass through while blocking others.
What is the movement of molecules through a cell membrane requiring energy?
active transport
What are molecules that helps control the movement of a substance through the cell membrane?
Proteins
What is the movement of water molecules through a sectively-permeable cell membrane?
osmosis
