What else can I help you with?
What cell part allows only certain substances to difuse into and out of the cell?
The cell's membrane allows only certain substances to diffuse in and out of the cell.
How is facilitated diffusion different than normal diffusion?
Diffusion is the movement of molecules or partocles from an area of high concentration to an area of lower concentration, and Facilitated diffusion is when substances difuse across cell membranes more rapidly than you might expect.
What is the opposite of cytoplasm?
In terms of the cell, the other major division that is non-cytoplasm is the nucleus.
Membrane activity most nearly opposite to exocytosis?
The membrane activity most nearly opposite to exocytosis is endocytosis. Endocytosis involves taking in substances from outside the cell by engulfing them with the cell membrane and forming vesicles to bring them into the cell, while exocytosis involves releasing substances from inside the cell to the outside by fusing vesicles with the cell membrane.
What's the direction sodium ions are pumped?
Sodium ions and potassium ions are pumped in opposite directions. Sodium ions are pumped out of the cell and potassium ions are pumped into the cell.
What cell part allows only certain substances to difuse into and out of the cell?
The cell's membrane allows only certain substances to diffuse in and out of the cell.
How is a electrolytic cell different from galvanic cell?
Electrons flow in the opposite direction.
How is electrolytic cell different from a galvanic cell?
Electrons flow in the opposite direction.
What is the direction of movement of various substances across the cell membrane for the cell's life activities?
excretion, transport and respiration
What is cell membrane pumps?
cell membrane pumps use energy to force molecules in a direction opposite of natural.
Compare and contrast endocytosis and exocytosion?
Endocytosis is the process by which cells take in substances by engulfing them with the cell membrane, forming vesicles that bring the substances into the cell. Exocytosis, on the other hand, is the process by which cells expel substances by fusing vesicles containing the substances with the cell membrane, releasing the substances outside the cell. Both processes involve the movement of materials across the cell membrane but in opposite directions.
How is facilitated diffusion different than normal diffusion?
Diffusion is the movement of molecules or partocles from an area of high concentration to an area of lower concentration, and Facilitated diffusion is when substances difuse across cell membranes more rapidly than you might expect.
What direction do electrons flow in a electrolytic cell?
Electrons flow from the negative electrode (cathode) to the positive electrode (anode) in an electrolytic cell. This is the opposite direction of conventional current flow.
What is the opposite of cytoplasm?
In terms of the cell, the other major division that is non-cytoplasm is the nucleus.
Membrane activity most nearly opposite to exocytosis?
The membrane activity most nearly opposite to exocytosis is endocytosis. Endocytosis involves taking in substances from outside the cell by engulfing them with the cell membrane and forming vesicles to bring them into the cell, while exocytosis involves releasing substances from inside the cell to the outside by fusing vesicles with the cell membrane.
How does passive transport move substances across a cell membrane in the direction of their concentration gradient?
Passive transport moves substances across a cell membrane in the direction of their concentration gradient without requiring energy input from the cell. This process relies on the natural movement of molecules from areas of high concentration to areas of low concentration, facilitated by protein channels or carriers in the cell membrane.
What is called when vesicle's are used to move substances into a cell?
It is called endocytosis, which is defined as "the transport of solid matter or liquid into a cell by means of a coatedvacuole or vesicle." The opposite of endocytosis is exocytosis.
