What else can I help you with?
The statement below refers to a structure of the cell oxygen diffuse through this structure but sodium ion may need active transport which structure is this statement most likely referring to?
a semipermeable membrane
What structure does oxygen diffuses through but a sodium ion may need active transport?
Oxygen can diffuse through the cell membrane, which is selectively permeable to small non-polar molecules. On the other hand, sodium ions are charged and larger, so they typically require active transport mechanisms such as protein pumps to move across the cell membrane.
What does active transport look like?
The only different between passive and active transport is the use of energy. In passive transport, molecules can either diffuse across the membrane, go through an aquaporin or use a passive transporter. In active transport, energy needs to be released, and it is usually because you are trying to transport a molecule or ion up its concentration gradient.
What helps molecules diffuse across membrane through transport proteins?
Transport proteins help facilitate the movement of molecules across a membrane by providing a specific channel or carrier for the molecules to pass through. These proteins can be selective, allowing only certain molecules or ions to pass through, and can also be regulated based on the cell's needs. Additionally, transport proteins can function through processes such as facilitated diffusion or active transport to move molecules in or out of the cell.
What structure does oxygen diffuses through but sodium ion may need active transport?
A semipermeable membrane
A molecule that can diffuse freely through a phospholipid bilayer is probably?
By Passive transport i can onlythink of glucose, but by active transport material like water, carbon dioxide, amino acids, sodium and potasium and of course oxygen! :)
Can small lipids diffuse into cell membrane through diffusion?
Yes, small lipids can diffuse through the cell membrane via simple diffusion. The lipid bilayer of the membrane is hydrophobic, allowing nonpolar and small molecules to pass through easily. This process does not require energy or specific transport proteins, enabling small lipids to move across the membrane freely. However, larger or polar molecules typically require facilitated transport or active transport mechanisms.
Is diffusion through ion channels a form of active transport?
Facilitated diffusion, or diffusion through ion channels, is not a form of active transport. It is a spontaneous passive transport.
What is used to move a substance through a membrane in active transport?
Electrochemical gradient is used to move substances through a membrane in active transport.
Why does oxygen diffuse into the blood instead of the active transport?
Oxygen is a small molecule that can easily diffuse across cell membranes, including the membranes of red blood cells. This passive diffusion process is faster and more efficient than active transport for molecules like oxygen that are able to freely move across cell membranes.
What is the type of transport in which a cell goes against the concentration gradient in order to diffuse substances within?
Active transport is the type of transport in which a cell moves substances against their concentration gradient, requiring energy to do so. This process helps maintain the internal balance of substances within the cell.
What is the definition of active transport?
active transport is an energy reqiuring process in which transport proteins bind with particles and move them through a cell membrane
