Asked in Genetics, Cell or Plasma Membranes
Mechanisms that require energy to move substances across to plasma membrane are called?
Active transport is the energy to move substances. The substances moves across the plasma membrane. ...
Asked in Human Anatomy and Physiology
What membrane components allow movement of non-polar substances across membrane?
Integral proteins allow movement of non-polar substances across membranes. ...
Asked in Biology
What is process that moves molecules across a cell membrane from regions of lower concentration to higher concentration?
Simple diffusion is the process of moving small substances across a cell membrane from where the concentration is higher to a place where it is lower. A specific term is used when this involves just water: osmosis. ...
Asked in Biology, Cell Biology (cytology)
How do animal cells exchange substances at a membrane?
They exchange substances across the membrane, either by simple diffusion or osmosis, or by active transport systems. ...
What membrane component helps substances move across the cell membrane?
The component that helps transfer substances across the membrane that I believe you are talking about, are the embedded protein channels. They help move larger particles across the cell membrane such as sodium because they are too large to move through the phospholipid bilayer. ...
Asked in Biology
What role does cellular membrane play in passive transport?
Cellular membranes are barriers to the diffusion of some substances. Diffusion across the membrane is called passive transport because no energy is expended by the cell in the process. Only the random motion of the molecules is required to move them across the membrane. ...
Asked in Genetics
The process specifically moves water molecules across a differentially permeable membrane?
The process that specifically moves water molecules across a differentially permeable membrane is known as osmosis. This is a common process in the cell membrane. ...
Asked in Cell Biology (cytology)
What is the voltage across a membrane called?
The chemical gradient refers to the imbalance of substances across the membrane. The Electrical Gradient refers to the difference of charges between substances on different sides of the Membrane. The Electrochemical Gradient refers to the combination of the previous two gradients. The short answer is MEMBRANE POTENTIAL. ...
Asked in Biology, Genetics, Cell or Plasma Membranes
What substances moves across the cell membrane with the help or carrier molecules?
The Subsances That Move Across The Cell Membrane WIth The Help Of Carrier Molecules are Blood ...
