Which transport process is the main mechanism of the movement of most macromolecules by body cells?
receptor-mediated endocytosis

What is diffision?
Diffusion is the process by which molecules move from an area of high concentration to an area of low concentration, resulting in a more even distribution. It is a passive transport mechanism that does not require energy input from the cell.
What is the process that requires the use of energy to move materials across a membrane?
Active transport is the process that requires the use of energy to move materials across a membrane. This process involves the movement of molecules against their concentration gradient, requiring energy input from the cell.
Proceeds Against a concentration Gradient requires a carrier?
Yes, the movement of molecules against a concentration gradient requires the use of a carrier protein or active transport mechanism in order to transport the molecules from an area of lower concentration to an area of higher concentration. This process requires energy to move molecules against their natural gradient.
What is the name if the movement of nutrients in the cells?
The movement of nutrients within cells is called intracellular transport. This process involves the movement of molecules and substances within the cell to where they are needed for cellular functions.
What is the name of the membrane that allows the movement of water and substances to move through the process of active transport and passive transport?
The cell membrane, also known as the plasma membrane, is responsible for regulating the movement of water and substances through processes like active transport and passive transport. It acts as a selectively permeable barrier, allowing certain molecules to pass through while blocking others.
Is the transport of macromolecules into a cell is called endocytosis?
Yes, the transport of macromolecules into a cell is called endocytosis. This process involves the cell membrane folding inward to form a vesicle that engulfs the macromolecules, bringing them into the cell. There are different types of endocytosis, including phagocytosis for large particles and pinocytosis for liquids. Overall, endocytosis is a crucial mechanism for cellular uptake of essential substances.
What transport mechanism is involved in the process in providing nutrients to a fetus?
transport absortion
What macromolecule is involved in facilitated diffusion?
Facilitated diffusion involves the transport of molecules across the cell membrane with the help of transport proteins. These transport proteins are typically made up of proteins, which are macromolecules. Therefore, macromolecules involved in facilitated diffusion are proteins.
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.
Which process movement of substances in organisms?
i want know the process of mass movement i want know the process of mass movement
The process by which land sinks with little or no horizontal movement is known as?
Atmospheric transport is the process by which land sinks with little or no horizontal movement.
What is diffision?
Diffusion is the process by which molecules move from an area of high concentration to an area of low concentration, resulting in a more even distribution. It is a passive transport mechanism that does not require energy input from the cell.
What is the movement of solutes from high concentration to low concentration until equilibrium is obtained?
This process is called diffusion. It is a passive transport mechanism where solutes move down their concentration gradient until equilibrium is reached. This movement occurs due to random molecular motion.
IS Active transportation a carrier of protein?
Active transport is not a carrier of protein; rather, it is a cellular process that moves molecules across a membrane against their concentration gradient, often requiring energy in the form of ATP. This process can involve transport proteins, such as pumps and carriers, that facilitate the movement of ions and small molecules. While proteins themselves can be involved in active transport, the term "active transport" refers specifically to the mechanism rather than the transport of proteins.
What is bulk transport in cells?
Bulk transport in cells is the movement of large quantities of molecules or particles across the cell membrane at once. This process helps in the efficient transport of substances such as proteins, polysaccharides, or even entire organelles. Bulk transport includes both endocytosis (taking in substances) and exocytosis (releasing substances).
What is the transport mechanism where a passive process pulls water from an area where there is more water to an area where there is less water?
osmosis
What is the transport mechanism necessary for the movement of oxygen from oxygen from the alveoli across the pulmonary capillary membranes into the blood?
The transport mechanism necessary for the movement of oxygen from the alveoli across the pulmonary capillary membranes into the blood is primarily diffusion. Oxygen diffuses from areas of higher concentration in the alveoli to areas of lower concentration in the blood within the pulmonary capillaries. This process occurs due to the partial pressure gradient of oxygen, where the oxygen concentration is higher in the alveoli than in the deoxygenated blood.
