What must a cell expand during active transport to accomplish movement of a substance?
During active transport, a cell must expand its energy in the form of ATP to pump molecules or ions across a membrane against their concentration gradient. This process requires energy to create a concentration gradient and move substances from low to high concentration.
When An ion must cross the cell membrane through active transport instead of passive transport when the ion is?
An ion must cross the cell membrane through active transport instead of passive transport when it is moving against its concentration gradient, meaning it is moving from an area of lower concentration to an area of higher concentration. Active transport requires energy, typically in the form of ATP, to facilitate this movement. This process is essential for maintaining cellular homeostasis and regulating ion concentrations within the cell.
What are passive transport active transport and endocytosis?
These are three different ways that cells have to get things in and out of the cell. Passive transport is movement without the use of energy, active transport requires energy.Active transport requires energy since the molecules are going toward a region that has a higher concentration of that molecule. The cell is 'stuffing' more into itself.Endocytosis means to 'take into the cell'. Usually this a larger molecule and cell must wrap part of itself around the molecule and then can bring it inside. This is a type of phagocytosis (cell eating).This requires energy as well.
Is sodium chloride passive transport or an active transport?
Active because concentration in cells must remain hight than in the blood.
What three major processes of nutrient absorption must be combined with a carrier molecule for transport?
The three major processes of nutrient absorption requiring a carrier molecule for transport are facilitated diffusion, active transport, and cotransport (symport). These processes are essential for the absorption of nutrients such as glucose, amino acids, and ions in the small intestine. The carrier molecules help transport these nutrients across the cell membrane.
A cell must expend energy to transport substances using?
A cell must expend energy to transport substances across its membrane against their concentration gradient, a process known as active transport. This energy is usually provided by ATP, the cell's main energy currency.

During active transport, a cell must expand its energy in the form of ATP to pump molecules or ions across a membrane against their concentration gradient. This process requires energy to create a concentration gradient and move substances from low to high concentration.
What is the transport of materials against a concentration gradient called?
The process of moving materials against a concentration gradient is called active transport. Active transport generally uses a protein pump to move molecules from an area of low concentration to an area of high concentration; in order to perform an active transport, the cell must use some of its energy to initiate the reaction.
When An ion must cross the cell membrane through active transport instead of passive transport when the ion is?
An ion must cross the cell membrane through active transport instead of passive transport when it is moving against its concentration gradient, meaning it is moving from an area of lower concentration to an area of higher concentration. Active transport requires energy, typically in the form of ATP, to facilitate this movement. This process is essential for maintaining cellular homeostasis and regulating ion concentrations within the cell.
The concentration of molecule x is greater inside a cell than outside. If the cell acquires x from its surroundings x must cross the cell membrane by mean of?
Active transport, which requires energy in the form of ATP. This process allows molecules to move against their concentration gradient from an area of lower concentration to an area of higher concentration.

What is the active transport and passive transport?
The requirements of passive transport through the cell membrane (phospholipid bilayer) of an animal cell are that the molecule is non-polar or small enough to pass by the non-polar phospholipid tails. This is because, for there to be passive transport, no energy must be used to transport the molecule from outside of the cell to inside.
Describe the process of active transport?
Active transport is when a protein moves a certain material across the membrane from a region of lower concentration to a region of higher concentration. This means the substance is absorbed against the concentration gradient and energy is needed for this active transport to work. The energy is usually comes from adenosine triphosphate or ATP, every cell supplies its own ATP by cell respiration. Globular proteins or pump proteins or transporter proteins in membranes carry out the active transport, the membrane must contain a lot of these proteins so that the cell can control the contents of its cytoplasm precisely. An example of active transport is in human nerve cells where potassium ions are pumped in and sodium ions are constantly transported out of the cell by active transport into the external fluid bathing the cell to build up a store of potential energy or an electrical impulse that is used to transmit a nerve impulse.
What type of transport is faciliated diffusion?
Neither of these require energy. Diffusion occurs naturally when a higher concentration of a substance exists on one side of a membrane than the other; molecules will enter into the area of lesser concentration until there is an equilibrium on both sides. Active transport requires the energy of the cell.
Compare the contrast pasive and active cell transport process?
Passive transport is when materials move through the cell membrane without using energy. Active transport is when materials move through the cell membrane using the cell's energy. During Active transport a protein called ATP helps the material get through the cell membrane.
