What else can I help you with?
Why is starch broken down outside the cell?
Starch is too big to enter cells, so it is broken down into smaller molecules like glucose outside the cell. These smaller molecules can then be transported into the cell for energy production.
What substances normally fail to cross cell membranes under any circumstances?
Large molecules such as proteins and polysaccharides typically do not cross cell membranes. Additionally, charged ions like sodium (Na+) and chloride (Cl-) may have difficulty passing through cell membranes due to their charge.
In general the net movement of small uncharged atoms and molecules through the membrane of a cell will occur until?
Molecules will move into or out of the cell until it becomes isotonic to its surroundings. This means that the concentration of the molecules inside the cell is equal to the concentration of the molecules outside the cell.
What controls the passage of molecules in and out of the cell?
Cell membrane controls the passage of molecules in and out of the cell through selective permeability. This allows specific molecules to pass through while preventing others from entering or exiting the cell. The cell membrane contains protein channels and pumps that regulate the movement of ions and molecules.
Which terms identifies the process used by the cell to remove large molecules?
The process used by cells to remove large molecules is called endocytosis. Endocytosis involves the cell engulfing the molecules by forming a vesicle around them, which then moves the molecules into the cell for processing or removal.
Does molecules have cell?
No, molecules do not have cell, rather a cell have molecules in it.
Why do molecules easily diffuse across a cell membrane while glucose molecules do not?
Glucose is too big to pass throught.
What explains why oxygen molecules diffuse across a cell membrane while glucose molecules do not?
Glucose is too big to pass through.
Why oxygen molecules do not across a cell membrane while glucose molecules do not?
Glucose is too big to pass throught.

Starch is too big to enter cells, so it is broken down into smaller molecules like glucose outside the cell. These smaller molecules can then be transported into the cell for energy production.
What statement explains why oxygen molecules easily diffuse across a cell membrane which glucose molecules do not?
Glucose is too big to pass throught.

Which part of the cell surrounds the cell and allows molecules in and?
The cell membrane is the thing that surrounds the cell. The cell membrane contains proteins that allow active transport of molecules in and out of the cell.
How big are molecules?
big
In which process in which process this is so you molecules does the cell use a vesicles to move molecules into the cell?
cells
What process does the cell use a vesicle to move molecules out of a cell?
Exocytosis is the process that moves molecules from the inside of the cell to the outside. This process uses sacs or vesicles to move the molecules out.
What process does a cell us a vesicle to move molecules out of a cell?
Exocytosis is the process that moves molecules from the inside of the cell to the outside. This process uses sacs or vesicles to move the molecules out.
