osmosis
This process, which involves the movement of water through a semipermeable membrane, is essential for regulating fluid balance in cells.
What is osmosis?
This process involves the movement of molecules across a cell membrane from an area of low concentration to an area of high concentration, requiring energy.
What is active transport?
This process allows molecules to move from an area of higher concentration to an area of lower concentration, without requiring energy.
What is passive transport?
This is the control center of the cell, containing genetic material in the form of DNA.
What is the nucleus?
This is the process by which cells engulf large particles or liquids by wrapping their membrane around them, forming a vesicle.
What is endocytosis?
The type of solution in which the concentration of solutes is the same inside and outside the cell, resulting in no net water movement, is called this.
What is an isotonic solution?
This molecule, produced in cells, provides the energy necessary for active transport to occur.
What is ATP (adenosine triphosphate)?
This type of passive transport occurs when small, nonpolar molecules like oxygen or carbon dioxide move directly through the lipid bilayer of the cell membrane.
What is simple diffusion?
This structure, made of phospholipids, surrounds the cell and regulates what enters and leaves.
What is the cell membrane (or plasma membrane)?
In this type of active transport, a cell expels materials by using a vesicle that fuses with the cell membrane.
What is exocytosis?
In this type of solution, the solute concentration is higher outside the cell, causing the cell to lose water and shrink.
What is a hypertonic solution?
This type of protein, embedded in the cell membrane, facilitates the movement of ions or molecules during active transport.
What is a pump protein?
In this form of passive transport, water molecules move through a semipermeable membrane, from an area of low solute concentration to high solute concentration.
What is osmosis?
This organelle is responsible for producing energy in the form of ATP and is often referred to as the "powerhouse" of the cell.
What are mitochondria?
This is the term for the movement of ions like sodium and potassium across the cell membrane, requiring ATP to maintain the cell's internal balance.
What is the sodium-potassium pump?
When a plant cell is placed in a hypotonic solution, water moves into the cell, causing the cell to become turgid. This pressure within the cell is called this.
What is turgor pressure?
The sodium-potassium pump is an example of active transport, where sodium ions are pumped out of the cell and potassium ions are pumped in. This maintains a balance of ions known as this.
What is the electrochemical gradient?
. This specific type of diffusion involves the movement of molecules like glucose or ions through a membrane protein, without energy input.
: What is facilitated diffusion?
. This organelle is responsible for making proteins by reading messenger RNA (mRNA) and linking amino acids together.
What are ribosomes?
. This process occurs when a cell takes in fluid from its surroundings by forming small vesicles from its membrane.
What is pinocytosis?
. Osmosis is crucial in the kidneys because it helps with the reabsorption of water from the filtrate back into the bloodstream. This process is a part of this major bodily function.
What is homeostasis?
In this type of active transport, the cell engulfs large particles or liquids by wrapping its membrane around them, forming a vesicle.
What is endocytosis?
This term describes the state that is reached when the concentration of molecules is the same on both sides of the cell membrane, resulting in no net movement.
What is equilibrium?
This structure is composed of protein filaments and helps maintain the cell’s shape, as well as aiding in cell movement and division.
What is the cytoskeleton?
The process by which ions like calcium or hydrogen are pumped against their concentration gradient using ATP is often critical for processes like muscle contraction.
What is proton pump or calcium pump?
