How do oxygen enter a cell?
Through the muscles
Through what structure does water oxygen and carbon dioxide can enter a cell?
Water, carbon dioxide and oxygen can enter a cell through the plasma membrane.
What can Water oxygen and carbon dioxide can enter a cell through?
Through the cell membrane.
What are the only materials that can enter the cell?
Oxygen, amino acid and glucose.
How many oxygen molecules need to enter or exit the cell to achive equilibrium?
. . . . . .
Where does glucose an oxygen come for to react in cellular respiration?
Glucose and oxygen enter a cell's cytoplasm for aerobic cellular respiration.
Does a cell wall allow oxygen and nutrients to enter and waste products to leave?
Yes it does
Does the cell membrane let sugar water and oxygen enter?
Yes, both are necessary for the cell to produce energy to function.
Do the carbohydrates you eat in the form of starch enter your cells?
No, they contain too much oxygen so they can't enter our cells. They do however sectrete chemicals, and these chemicals enter the cell
How does the cell wall help the cell?
Prevents foreign material from entering the cell; and allows nutrients and oxygen to enter while letting metabolites (waste or functional chemicals) out.
How does oxygen and carbon dioxide enter and leave the cell?
By passive diffusion down its concentration gradient, which requires no energy expenditure from the cell. Basically, if you have more oxygen outside a cell than inside a cell, it travels through channels or holes in the cell membrane until the concentration of oxygen is equal inside and outside the cell.
How do cells resist oxygen toxicity?
Cells resist oxygen toxicity because of the semi permeable membrane. This controls the amount of molecules and what molecules enter the cell.
