Passive transport in biological systems is a process where molecules move across a cell membrane without the use of energy. This can happen through diffusion, where molecules move from an area of high concentration to low concentration, or through facilitated diffusion, where molecules are helped across the membrane by specific proteins. This process is important for maintaining the balance of molecules inside and outside of cells.

What is the function of passive transport?
Passive transport is a biological process that allows molecules to move across a cell membrane without the use of energy. It occurs down the concentration gradient, from an area of high concentration to an area of low concentration. Common types of passive transport include simple diffusion, facilitated diffusion, and osmosis.
What is the main difference between active trasport and passive transport?
Active transport requires energy (ATP, GTP, etc) to work against the electrochemical gradient. Passive transport works with the electrochemical gradient and does not require energy. (Think diffusion)
A form of passive transport that uses transport proteins-?
Diffusion (passive transport) needs no energy to take place, and therefore no need for transport or carrier protiens. Active transport uses carrier protiens, as the cell needs to work against a concentration gradient. This requires energy. Diffusion can take place outside of cells Active transport can't take place outside of cells.
How do active and passive transport help maintain homeostasis?
Active transport uses energy to move molecules against their concentration gradient, helping to maintain proper levels of ions and nutrients inside cells. Passive transport allows molecules to move down their concentration gradient without energy input, helping to maintain balance and stability in the cell's environment. Together, active and passive transport mechanisms work to regulate the flow of essential substances in and out of cells, contributing to overall homeostasis.
Give two differences between active transport and passive transport?
Active transport requires energy, passive transport just happens. If there is more of a certain molecule on one side of a membrane than the other, molecules that CAN fit through the membrane will do, so the concentration will even itself out. No work has to be done to achieve this. SO when you breathe in, oxygen just diffuses across from the air into your blood, because there's plenty of it in the air. But if a plant needs to get say magnesium from the soil (which it needs to make chlorophyll) then it is not going to get much by diffusion, because there's not much in the soil and probably more in the plant. It will need to use active transport ie a protein in the cell wall will pick up the substance wanted and flip it into the cell, and this costs the cell some energy.
A sentence for the word passive transport?
Passive transport refers to the movement of molecules across a cell membrane. An example of a sentence would be: "Passive transport does not require energy to work".

What is biological work?
Biological work is work that entails the use of biological knowledge. Biological knowledge is data generated through biological research. Biological research is any study that makes a contribution to the field of Biology

Which system work together to transport carbon dioxide out of the body?
the circulatory and the excretory systems

What Handles work in passive?
Handles work in passive, inefficient way
What body systems work together?
The respiratory and circulatory systems work together to transport oxygen to the cells and remove carbon dioxide. The nervous and muscular systems work together to control movement. The endocrine and reproductive systems work together to regulate hormone production for reproduction.
Explain the difference between passive transport and active transport Give several types of each and explain how they work?
when molecule travels from a higher concentration to a lower concentration through a concentration gradient.It is known as passive transport. Active transport refers to when molecule travels from a region of lower concentration to a region of higher concentration against the concentration gradiet. Transport of protein is an active transport. Fit it in the sentence your way
What kind of person Handles work in passive inefficient way?
Handles work in passive, inefficient way
