What else can I help you with?
Osmosis in cells?
it occurs when water moves across a membrane to a lower concentration from a higher concentration.
What is a substance that moves across a cell membrane without using the cells energy tends to move?
away from the area where it is more concentrated
How is diffusion used when cells remove carbon dioxide?
Carbon dioxide moves out of the cells from a higher to lower concentration across the cell membrane. Then the CO2 moves through the capillary wall across the diffusion gradient. The diffusion process is repeated at the capillary/alveolar junction.
What is the process which water moves across the cells membrane?
Water moves across the cell membrane through osmosis, which is the passive movement of water molecules from an area of higher concentration to an area of lower concentration through a selectively permeable membrane. Osmosis helps maintain the balance of water and solutes inside and outside of the cell.
What helps moves things across the membrane?
transportation
Which one moves faster across the cell membrane the large or the small?
Small particles move faster across the membrane.
What are the three examples of molecules that a cell would want to be able to move effectively across its membrane?
Oxygen: Cells need oxygen for cellular respiration and energy production. Oxygen moves across the cell membrane through passive diffusion to reach the mitochondria. Glucose: Glucose is a vital source of energy for cells. It requires transport proteins, such as glucose transporters, to move efficiently across the cell membrane. Water: Water is crucial for various cellular processes. It moves across the membrane through specialized channels called aquaporins, allowing cells to regulate their hydration levels and maintain homeostasis.
How does the material move from the respiratory system to the circular system?
Material moves from the respiratory system to the circulatory system by diffusing across a membrane in the air sacks called alveoli.
When water moves across a cell membrane it is called?
osmosis
What sugar moves across the cell membrane by facitated difusion?
Glucose
What is it when water moves across a cell membrane?
When water moves across a cell membrane, it is called osmosis. Osmosis is the passive movement of water molecules from an area of higher concentration to an area of lower concentration through a selectively permeable membrane.
What moves marerials across the plasma membrane in the direction of the concentration?
Active transportation is the material that across plasma membrane. This makes it flow one way.
