What else can I help you with?
How does an amoeba breathe?
Amoebas take in oxygen through a process called diffusion, where oxygen molecules move into the cell across its cell membrane. The oxygen then reacts with other molecules in the cell to produce energy for the amoeba to survive and carry out its functions.
Can oxygen diffuse across a cell membrane?
No, oxygen cannot directly diffuse across a cell membrane. Instead, it crosses the cell membrane with the help of specific transport proteins, such as aquaporins and oxygen channels. These proteins facilitate the movement of oxygen from areas of high concentration to low concentration.
How an amoeba exchanges oxygen and carbon dioxide gases with its surroundings?
diffusion across their body surface (cell surface membrane)
Do large cells move across the cell membrane quickly?
A large cell will never move across an intact cell membrane.
How does the cell transport materials across the cell membrane?
a cell transports things across the cell membrane from areas of high concentration to ares of low concentration
When does diffusion occur across a cell membrane?
Diffusion across a cell membrane occurs when concentrations of a substance are higher either inside or outside the cell.
How I can use cell membrane in a sentences?
cell membrane is the most outer part of a cell. cell membrane is very big in surface.
What is antiport system?
An antiport system is a type of transport system in cells where two or more different molecules or ions are exchanged across a cell membrane in opposite directions. This process is also known as countertransport. Antiport systems are essential for maintaining ion gradients and transporting molecules across the cell membrane.
What does diffusion do in a cell?
Move things across the cell membrane.
What does a carrier protein do in the process of transporting molecules across a cell membrane?
A carrier protein helps transport molecules across a cell membrane by binding to specific molecules and changing shape to move them across the membrane.
What material diffuses across the cell membrane during osmosis?
Water molecules diffuse across the cell membrane during osmosis. Osmosis is the movement of water from an area of high concentration to an area of low concentration, across a semi-permeable membrane. This process helps maintain the balance of water inside and outside the cell.
What is the transport of water across the cell membrane called?
Movement of water across a membrane is called OSMOSIS.
