What else can I help you with?
Is the following sentence true or false active transport always requires transport proteins during the process?
false
What are the similarities between passive and active transport?
They are both mechanisms for transporting molecules across the cell membrane. There aren't really that many other similarities. Active transport requires energy in the form of ATP molecules and is often against a concentration gradient, whereas passive transport happens along a concentration gradient and requires no energetic input from the organism.
What is the differnce between active and passive transport?
passive doesn't neeed energy but active transport does
What is the movement of a substance against the substances concentration gradient?
Active transport, or reverse osmosis; depending upon conditions.
How does insulin bring sugar down to normal levels after a meal?
insulin acts as a key to turn on the active transport of sugar across cell membranes.
What is the Method of movement that requires the expenditure of ATP molecules is?
The movement that requires the expenditure of ATP molecules is called active transport. In active transport, cells use ATP to move molecules or ions against their concentration gradient, ensuring that specific substances are taken up or expelled from the cell as needed. This process is essential for maintaining cellular functions and homeostasis.
Active transport systems are a form of cell transport that requires energy from molecules of what?
Wording is a little confusing but I believe the energy-providing molecule you're after is ATP (Adenosine Triphosphate)
What ways of moving molecules across a membrane requires energy?
Active transport requires energy to move molecules across a membrane against their concentration gradient. This process is facilitated by specific carrier proteins embedded in the membrane that use energy, usually in the form of ATP, to transport molecules.
What id the difference between active and passive transport?
Active transport requires energy to move molecules against their concentration gradient while passive transport does not require energy and moves molecules from high to low concentration. Active transport is selective and can transport specific molecules, while passive transport is nonselective and moves molecules based on their concentration gradient.
What is the function of active transport in moving small molecules and ions across the membranes?
the movement of materials against a concentration difference is known as active transport. Active transport requires energy.
What are passive and active transport?
Passive transport is the movement of molecules across a cell membrane without requiring energy, such as diffusion and osmosis. Active transport, on the other hand, requires energy to move molecules against their concentration gradient, typically using protein pumps or transporters.
What is the movement of molecules across a membrane against their concentration at the expense of ATP energy called?
Active transport. It requires energy in the form of ATP to move molecules against their concentration gradient.
Does active transport require a transport protein?
Active transport requires the use of ATP because in active transport things move against the concentration gradient. Usually there is a protien pump (which is a form of a transport protien) that does this.
What type of transport requires energy move a molecule?
Active transport requires energy to move a molecule.
Active transport requires energy because it usually involves the movement of what substances?
Molecules
What is the function of active transport moving small molecules and ions across cell membrane?
the movement of materials against a concentration difference is known as active transport. Active transport requires energy.
Which process requires energy to bring molecules across the cell membrane?
Active transport requires energy to move molecules across the cell membrane against their concentration gradient. This process is carried out by specific proteins called pumps that utilize cellular energy in the form of ATP to transport molecules.
