What type of molecules embebbed in the plasma membrane allows molecules to pass through the membrane by active or passive transport?
proteins
What helps molecules diffuse across membrane through transport proteins?
Transport proteins help facilitate the movement of molecules across a membrane by providing a specific channel or carrier for the molecules to pass through. These proteins can be selective, allowing only certain molecules or ions to pass through, and can also be regulated based on the cell's needs. Additionally, transport proteins can function through processes such as facilitated diffusion or active transport to move molecules in or out of the cell.
What is passive transport cite examples?
Passive transport is the movement of molecules across a cell membrane without the use of energy. Examples include simple diffusion, where molecules move from an area of high concentration to low concentration, and facilitated diffusion, where molecules pass through a membrane with the help of transport proteins.
What is the defference between active transpors and passive transport?
Active transport requires energy input to move molecules against their concentration gradient, while passive transport moves molecules along their concentration gradient without energy input. Active transport is typically carried out by transport proteins, such as pumps, while passive transport can occur through simple diffusion or facilitated diffusion.
How are the smaller molecules o2 and co2 able to pass through the openings of the cell membrane?
passive transport by diffusion
What is a passive trasport?
Passive transport is the movement of molecules through cell membranes with out the use of energy by the cell
Is transport through aquaporin passive or active?
Transport through aquaporins is passive, as water molecules move across the cell membrane through these channels driven by osmotic gradients without the need for energy expenditure.

What type of transport is it when gluclose molecules move into a cell?
Glucose molecules entering a cell typically occurs through facilitated diffusion, which is a type of passive transport. This process involves the movement of glucose across the cell membrane with the help of specific transporter proteins.
What type of molecules embebbed in the plasma membrane allows molecules to pass through the membrane by active or passive transport?
proteins
How do carriers proteins facilitate passive transport of molecules across a membrane?
Carrier proteins facilitate passive transport of molecules across a membrane by changing its shape, by using ATP, to allow a substance to pass through the membrane.
How is active transport different from passive transport, and what are two ways in which they contrast in terms of their mechanisms?
Active transport and passive transport are two methods by which substances move across cell membranes. Active transport requires energy input from the cell, usually in the form of ATP, to move molecules against their concentration gradient. In contrast, passive transport does not require energy and relies on the natural movement of molecules from areas of high concentration to low concentration. One way in which active and passive transport contrast in terms of their mechanisms is that active transport uses specific carrier proteins to transport molecules, while passive transport can occur through simple diffusion or facilitated diffusion. Another difference is that active transport can move molecules in both directions across the membrane, while passive transport typically only moves molecules in one direction.
What proteins are used in both active and passive transport?
Transport proteins such as ion channels and carrier proteins are used in both active and passive transport processes. Ion channels move ions down their concentration gradient through passive transport, while carrier proteins can facilitate passive transport by allowing molecules to move along their concentration gradient, or active transport by requiring energy to transport molecules against their concentration gradient.

How do molecules move by passive transport?
Molecules move by passive transport down their concentration gradient, from an area of higher concentration to an area of lower concentration, without the input of energy. This can occur through simple diffusion, facilitated diffusion, or osmosis, depending on the properties of the molecules and the cellular environment.
Can water enter a cell by active transport?
There are two ways that the molecules (i.e: water) move through the membrane: passive transport and active transport. Active transport requires that the cell use energy that it has obtained from food to move the molecules (or larger particles) through the cell membrane. Passive transport does not require such an energy expenditure, and occurs spontaneously.
