How does a large particle leave a cell by a active transport?
Autumncold
It requires energy, and a protein carrier molecule. The large particle binds to the protein carrier on the inside of the cell. It is then transported across the membrane as a result of a conformational change in the protein (think of it flipping), and then it is released on the outside of the cell. Again, this requires some source of energy.

How does as large particle leave a cell using active transport?
It requires energy, and a carrier protein. The large particle binds to the carrier protein on the inside of the cell. The protein then changes conformation, thus moving the particle to the outside, where it is dropped off by another conformational change in the protein.
DO BETA particles cause ionisation?
yes, a BETA particle is an electron. As these leave the isotope, it becomes a positive ion of the substance it began as.
Do alpha particles consist of two protons and two neutrons?
No. A beta particle is either an electron (beta-) or a positron (beta+). An alpha particle consists of 2 protons and 2 nuetrons bound together. It's actually a helium-4 nucleus that has been emitted as a result of nuclear decay. Both types of beta particle and the alpha particle are forms of particulate radiation that result from nuclear decay of radioactive materials. Which form of decay and the energies of the particles as they leave the nucleus vary as the radionuclide emitting them.
What happens after the reaction center receives energy from molecules in the light harvesting complex?
It passes the energy to the reaction center ( a specialized region of photosystem) then the energized electrons leave the reaction centers and are passed to adjacent electron transport chains (ETC)
What is a low-order detonation?
A low-order detonation is either incomplete detonation or complete detonation at lower than maximum velocity -OR- leave large ordanance fragments containing explosives and may leave chunks or pieces of exposed explosive; do not move remaining debris

Type of active transport that moves large particles into a cell through vesicles?
Endocytosis - the way in which cells take in food and other materials. The cells membrane wraps around the particle it needs on its outside, ingesting it. This then becomes trapped within a vacuole inside the cells cytoplasm where it is broken down, digested, and absorbed by enzymes.
What transport leave the cell without the use of energy?
Passive Transport, and if your dealing with liquids its is Osmosis. Passive Transport is the act of transport with no use of energy: hence the word "Passive." But Active Transport is when it does use energy: hence the word "Active."
What Is the process which material enter and leave the cell through the cell membrane?
Either active transport, passive transport, or facilitated diffusion
What is the process by which materials enter and leave the cell through the cell membrane?
Either active transport, passive transport, or facilitated diffusion
Are osmosis and endocytosis passive transports?
It is an active transport,Transport mechanisms fall into two catagories passive and active. Passive transport mechanisms do not require the cell to do work for the substance to enter or leave the cell. Instead the energy involved comes from the kinetic energy of the molecules in solution. Active transport mechanisms involve the cell to use cellular energy usually in the form of ATP to power special protein pumps to bring material into the cell.Passive transport mechanisms Active Transport mechanismsSimple diffusionOsmosisFacilitated DiffusionSimple protein channelsGated channelsActive transport via protein pumpsBulk flow mechanismsendocytosisphagocytosispinocytosisexocytosisThe passive transport mechanisms and the protein pump mechanisms involve movement of substances as single molecules across the membrane. The "bulk" flow mechanisms endocytosis and exocytosis enable the cell to take in very large packages of molecules...say a food item from the environment. Many books treat these bulk flow mechanisms as separate from active transport for that reason.
What 3 ways can substances enter and leave a cell?
Substances can move in and out of a cell in several ways. Diffusion is when a substance will distribute itself in or out of a cell until the distribution on both sides of the cell is balanced. Active transport is when a cell transports a substance across the cell membrane that would not normally be able to pass through. Osmosis is the movement of water from areas with few dissolved dissolved substances to areas with high dissolved substances.
Is a carrier protein an active transport or a passive transport?
They are used in both, in passive the molecules move in , then change the shape then leave and the entering and leaving are both by diffusion. in active transport molecules move in by diffusion, change the shape of the carrier protein, then because theyre moving into the cell where the molecule is in higher concentration energy is required to push the molecules out of the carrier proteins, this energy comes from ATP which is supplied to the carrier proteins.
What is the process called after proteins are made by ribosomes and they leave the cell?
Copies of DNA do not leave the cell, they split, rebuild into two daughter copies, and then separate into opposite sides of the cell, which then divides. The DNA never passes the plasma membrane of the cell. Answer In vessicles.
What is the idiom word of ad-leave?
Active Duty Leave
Cell membranes are semi-permeable and allows small substances to go in but what if the cell needs the large substances and does not want the smaller substances?
The cell would dispose of the smaller substance later. There are generally two types of mechanisms that allow a cell to move substances across the cell membrane. One is called active transport and the other is passive transport. In passive transport the cell membrane is semipermeable and allows substances of smaller sizes to enter or leave the cell by diffusion, filtration, or osmosis. In active transport the cell membrane uses energy in the form of ATP molecule to move either atoms, molecules, or even larger things like parts of other cells, bacteria, or virus across the membrane. With the larger particles, the cell wall actually engulfs the object, surrounds it, and then collapses onto it so it is inside the cell. Then organelles called lysosomes, eat away at the foreign particle until it breaks down and gets digested inside the cell. These processes are called phagocytosis (for solids) and pinocytosis (for liquids).
What is the active form of Your cares are left behind?
"You leave your cares behind" is active voice.
