How do stars make radiant energy?
Thermonuclear fusion in the core of the star heats the material of the star. A series of complex energy transfer mechanisms transport the heat from the core to the photosphere of the star. The photosphere then emits electromagnetic radiation.
What is the purpose of the speed of light?
The purpose of any speed is to transport objects or energy from place to place. In the case of light, the transport of energy occurs quite rapidly.
Sound waves cannot travel through empty space because they need particles to transport what?
to transport the sound or the sound energy.
What type of energy transport is occurring just below the photosphere?
convection
Explain Why the sun is major source is energy?
Sun is the source of heat and light energy. It provides energy on earth's surface.
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.
Diffusion and Osmosis are passive transport mechanisms meaning they do not require?
They do not require energy, which is often in the form of ATP.
What is an outside source of energy is required for?
active transport
What is the movement of material through a membrane?
This movement occurs through several mechanisms.
Why does it take energy to transport some things across the cell but it doesn't take energy to transport other things?
there are two ways to transport things into a cell: active and passive transport. In active transport the cell has to physical engulf whatever it needs from outside the cell. In passive transport, if something inside the cell has less of the item that is outside of the cell, the things outside of the cell go into the cell until the number is balanced. This happens automatically so it doesn't involve energy.
What is the movement of materials through a cell membrane?
Movement of substances into and out of cells include passive mechanisms that do not require cellular energy (diffusion, facilitated diffusion, osmosis, and filtration) and active mechanisms that use cellular energy (active transport, endocytosis,and exocytosis).
Why transport proteins require energy to function in active transport?
Because there is a higher concentration inside the cell then out side ....because it requires energy to move the molecules outside in a different direction then they would normally move, it is like riding a bike up a hill it requires energy.
What is the name of the process of how things get in and out of the cell?
The process by which substances enter and exit the cell is called cellular transport. It primarily occurs through two main mechanisms: passive transport, which does not require energy, and active transport, which requires energy expenditure by the cell. Examples of passive transport include diffusion and osmosis, while examples of active transport include endocytosis and exocytosis.
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.
What makes passive transport passive?
Passive transport is called passive because it doesn't require chemical energy intervention to occur. The four main types of passive transport are diffusion, facilitated diffusion, osmosis, and filtration.
How are active transport and passive transport different from each other?
The most basic difference between active and passive transport is that active requires energy while passive does not. You would require active transport if the substance is going against the concentration of molecules inside and outside of the membrane or if the substance is particularly large. Passive is more for smaller molecules that go with the concentration of the molecules inside and outside of the membrane.
