What else can I help you with?
There are two main ways in which molecules are transported into and out of cells - active transport and passive transport. Which of the following statements is true of passive transport?
Carrier proteins are sometimes used during passive transport.
How carbon dioxide water and sodium ions are transported across the cell membrane by both passive and active transport?
Carbon dioxide can diffuse passively through the cell membrane due to its small size and nonpolar nature. Water molecules can pass through the membrane via osmosis, a type of passive transport. Sodium ions are transported against their concentration gradient through active transport processes such as sodium-potassium pumps that require ATP for energy.
How is oxygen transported in the cell?
by active and passive transport via cell membrane proteins
How is water transported across the membrane?
Water is transported by a passive transport called osmosis. Osmosis is diffusion of water across the membrane.
Does passive transport require sugar?
Passive transport does not require sugar. Passive transport is a process by which molecules move across a cell membrane without the input of energy, such as diffusion or osmosis. Sugar molecules can be transported passively, but the process itself does not depend on sugar.
Does passive transport requires the use of ATP?
Active transport requires ATP and a transport channel. The channel is made of proteins.
Is sugar a osmosis passive transport or active transport?
Sugar is typically transported across a cell membrane using passive transport mechanisms like facilitated diffusion or simple diffusion. These processes do not require energy input from the cell. However, in some cases, active transport mechanisms such as the sodium-glucose cotransporter may be involved when sugars need to be transported against their concentration gradient, requiring energy.
Is diffusiona type of passive transport or active transport?
Passive transport is where materials are transported across a membrane without the use of stored energy. Active transport is where materials are transported across a membrane using ATP, or another source of stored cellular energy. Diffusion is where solutes flow across a membrane in response to a concentration gradient, and requires no energy input to occur. Therefore, diffusion is a form of passive transport.
Is transport proteins active transport or passive transport?

Facilitated diffusion is a example of?

Does glucose enter a cell by active transport?
GLUT1 is a passive protein transport. Glucose with GLUT1 can only be transported from high to low concentration. With the sodium - glucose symporter it's possible to transport glucose from low to high concentration.
Is transport proteins a passive transport?
Carrier proteins can be involved in passive transport.
