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.
What proteins are used in active and passive transport?
cell membrane
What facilities passive transport across a cell membrane?
Passive transport across a cell membrane is facilitated by proteins such as channel proteins and carrier proteins. These proteins allow the movement of ions and small molecules down their concentration gradient without requiring energy input from the cell. Lipid bilayer also plays a role in facilitating passive transport for small, non-polar molecules.
What perform active transport cells use?
Energy, versus passive in which energy is not used.
What form of passive transport always requires membrane-bound proteins?
Facilitated diffusion
Is transport proteins a passive transport?
Carrier proteins can be involved in passive transport.
Is transport proteins active transport or passive transport?
passive
Passive transport with the aid of transport proteins is what?
facilitated diffusion
What type of transport is carbon dioxide passive or active?
Carbon dioxide transport is passive because it moves across cell membranes by simple diffusion, down its concentration gradient. However, in the blood, most carbon dioxide is carried in the form of bicarbonate ions, which is facilitated by specific enzymes and transport proteins.
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.

What proteins are used in active and passive transport?
cell membrane
What are examples of passive transport and active transport?
Proteins that carry out passive transport include channel proteins and carrier proteins. Passive transport is "passive" because it does not use energy. The use of passive transport is also called "facilitated diffusion." Proteins that carry out passive transport includes the proton pump and the sodium-potassium pump; these require energy to function.
What is the role of transport proteins in active transport?
Active transport requires energy, unlike passive transport. The carrier proteins in active transport act as a "pump" ( fueled by ATP) to carry/attach themselfves to useful proteins for the cell.
Carrier proteins are sometimes used during passive transport.?
yes
Are all proteins enzymes Explain your answer?
No, not all proteins are enzymes. Enzymes are a type of protein that catalyze specific biochemical reactions. While many enzymes are proteins, there are also non-enzymatic proteins that serve structural, regulatory, or transport functions in the body.
Which type of passive transport involes the movement of molcoules via special transport proteins?
facilitated diffusion
