What is a series of folded membranes that moves materials around in a cell?
The mitochondria
A non-energy requiring process that moves materials across a cell membrane with the concentration gradient.?
The process of moving materials across the cell membrane without the expenditure of energy is called passive transfer
The nuclear membrane is allowing materials to pass through?
A cell controls what moves through the membrane by means of membrane proteins embedded in the phospholipid bilayer.The things that can easily move in and out of the cell through the membrane are gases, like oxygen and carbon dioxide, and water.
What moves through a semipermeable membrane into an area of what concentration?
Water moves through a semipermeable membrane from an area of high to low concentration. This is called osmosis.
What are the functions of the endoplasm?
The endoplasmic reticulum is a folded membrane what moves about the cell. It extends from the nucleus to the cell membrane. It is responsible for the production of the protein and lipid. Ribosomes also make proteins.
The process that moves materials through a membrane against a concentration diffrence is known as?
This process is known as active transport; needing ATP energy to complete the process.
What moves materials in a cell membrane without using energy?
Passive transport is the process in which dissolved materials move across a cell membrane without using a cell's energy.
Why does water pass quickly through cell?
it moves through aquaporins in the membrane.
What book transport process moves materials into cells?
The process that moves materials into cells is called endocytosis. During endocytosis, the cell membrane surrounds particles or substances outside the cell, forming a vesicle. The vesicle then fuses with the cell membrane and releases its contents into the cell.
What is a structure that moves material through a cell?
it's the cell membrane
What creates selective permebility of plasma membrane?
It is because of the make up of the membrane. Most of the bilayer is hydrophobic; therefore water or water-soluble molecules do not pass through easily. Other do pass through easily. A cell controls what moves through the membrane by means of membrane proteins embedded in the phospholipid bilayer.
What moves materials through cells from high concentrated areas to low concentrated areas?
Osmosis diffusion, osmosis is with water thrugh a semi permiable membrane, it uses no energy. diffusion is the answer.
