What are all the differences between active and passive transport?
Passive transport occurs when the concentration of something on one side of membrane is different from the concentration on the other side. It occurs when that substance can pass through the membrane, and always in the direction of more -> less. No energy is required to make the substance move; in fact, this movement generates energy. This is like rolling a rock down a hill--it just does it on its own.Active transport occurs in the opposite direction, from less -> more. It requires energy for transport. This is like rolling a rock up a hill--you have to push it the entire way!Both involve the transport of a substance across a membrane, and the change in concentrations on different sides of a membrane. Both are also important to the proper functioning of a cell.Active transport requires energy, but passive transport requires none.Active transport requires a special protein to make the transport occur, but passive transport requires none.
active transport reguires?
Active transport requires some form of energy input, usually ATP
What is the importance of Active Transport in living organisms?
Active transport is important in living organisms because it allows them to transport molecules against their concentration gradient, from an area of low concentration to an area of high concentration. This process requires energy to be expended by the cell, usually in the form of ATP. Active transport is crucial for maintaining proper ion concentrations and nutrient uptake in cells, thus enabling cellular functions and overall organismal survival.
What is the energy source for co-transport?
The energy source for co-transport is typically the concentration gradient of one substance that is established by an active transport process. This concentration gradient drives the movement of another substance against its own concentration gradient through a symporter protein.
What is carrier-assisted transport?
Carrier-assisted transport is a mechanism in which a carrier molecule assists in the movement of a substance across a biological membrane. The carrier molecule can bind to the substance and facilitate its transport across the membrane. This process is typically passive and does not require energy input from the cell.
Explain active transport?
Active transport is the movement of a substance against its concentration energy.
What is the cellular movement of a substance that does NOT require energy?
Passive transport
Is vesicular transport active or passive?
The contractile vacuole collects water, then pumps it out of the cell. It requires energy to be expended, so it is a type of active transport.
What is the power expended when a barbell is lifted 2.2m in 2 seconds?
The power during the lift is (weight of the barbell in Newtons)/4.4 watts.Note:Power is not "expended". Energy is. Power is the rate at which energy is expended.
What is difference between active transport and passive transport?
One difference is energy consumption. Active transport requires the cell to expend energy, while passive transport does not. Active transport is movement from a lower concentration to a higher concentration and passive transport is movement from a higher concentration to a lower concentration. Active transport is the movement of molecules across a membrane requiring energy to be expended by the cell. Passive transport is diffusion across a membrane requiring only random motion of molecules with no energy expanded by the cell. Active transport requires ATP to transport materials. Passive transport does not require ATP input to transport materials. Ex: diffusion

Movement of a substance across a cell membrane using chemical energy occurs during?
Active transport is the movement of a substance across a cell membrane using chemical energy. This process requires the use of a carrier protein and ATP to transport molecules against their concentration gradient.
How does facilitate transport differ from active transport?
Facilitated transport occurs when a substance moves from an area of higher concentration to an area of lower without the aid of energy. Active transport involves additional energy as it is moving from a lower concentration into a higher concentration.
What does expended mean?
It means the same as spent. Money which is expended is spent. A battery which is expended is spent; it has been used up.
active transport reguires?
Active transport requires some form of energy input, usually ATP
What name do you give to a substance to release energy?
A substance to release energy is usually called a fuel. A chemical reaction that releases energy is called exothermic.
