What is the difference between active and passive cellular transport?
Active transport requires energy; passive transport does not.
Passive and active transport?
Active Transpot. -Pumps -Endocytosis -Exocytosis Passive Transport - Diffusion -osmosis -Facilitated Diffusion active requires energy passive doesnt. active against concentration gradient, passive along concentration gradient.
Give a real life analogy to diffrentiate between passive transport?
Passive transport is like a door swinging freely on its hinges allowing people to move in and out without requiring energy. For example, osmosis is a passive transport process where water molecules move across a semi-permeable membrane from an area of high concentration to low concentration without the cell using energy.
Does active transport use oxygen?
Active transport (or active uptake, as we learnt it ) is moving against the concentration gradient. This requires energy which is why the oxygen is needed (the oxygen producing energy through respiration). It is affected by the concentration of oxygen because the more oxygen, the more energy produced, the faster the process occurs. Diffusion is not affected by the concentration of oxygen because it does not require energy to occur.
How does a cell membrane allow nutrients to get in?
The cell membrane is semi-permeable, which means that it allows certain substances to go through.For substances that are too large, there are vacuoles and transport proteins that assist the large substances.There is also facilitated transport, passive transport, and active transport. Passive transport is the only one where substances can go through the membrane without the cell expending energy.
Does osmosis require a carrier?
NO. Osmosis( by definition) is the DIFFUSION of water from a high concentration gradient to a low concentration gradient across a semipermeable membrane. As diffusion is a form of passive transport, it doesnt require a carrier
How are facilitated diffusion and active transport similar ad how do the differ?
both these processes do the transport against the concentration gradient uh no facilitated diffusion doesnt go against the gradient, the similiarity is that they both use carrier protiens
Active transport always requires?
Active transport always requires the use of energy (usually in the form of ATP) to move molecules or ions against their concentration gradient, from an area of lower concentration to an area of higher concentration. This process is essential for maintaining cell homeostasis and regulating the internal environment of the cell.
Why the sentence he comes to school doesnt have passive form when it has subject verb and object as sentence syntax?
In English, the passive voice is formed by using a form of "be" + past participle of the main verb. In the sentence "He comes to school," the verb "comes" is in active form. To change it to passive, you would have to rephrase it like "School is attended by him."
Why is the energy expended during endocytosis worth it?
Endocytosis is the bulk transport of materials into a cell, using energy in the form of ATP. It is an active process, and the energy is used to move the membranes around the materials to form the vesicles that are needed, and to move the vesicles into the cell.
Where does active transport occur in the excretory system?
Active transport occurs in the nephron of the excretory system, particularly in the proximal convoluted tubule and the distal convoluted tubule. This process involves the movement of solutes against their concentration gradient using energy derived from ATP.
What is an energetic Pokemon?
A very active one,it doesnt keep still
