What oranelles are membrane sacs used to transport molecules?
The organelles that are membrane sacs used to transport molecules are vesicles. These small, membrane-bound sacs can carry various substances, including proteins and lipids, within the cell or to the cell membrane for secretion. Vesicles play a crucial role in processes such as endocytosis, exocytosis, and intracellular transport. Additionally, they can be involved in the storage and transport of enzymes and other biomolecules.
What kind of molecule is used to transport molecules across the membrane?
hydropolactive.
ATP is being used to move the molecules out of the cell by?
ATP is being used to move molecules out of the cell by providing energy to transport proteins in the cell membrane. These proteins use ATP to change shape, allowing them to pump or transport molecules against their concentration gradient. This process is called active transport.
Where does energy used to transport molecules across a membrane from?
The energy used to transport molecules across a membrane comes primarily from the hydrolysis of ATP (adenosine triphosphate) molecules. This process, often mediated by membrane proteins such as transporters and pumps, allows cells to regulate the movement of substances in and out of the cell against their concentration gradients.
Carrier molecules in the plasma membrane are only required for active transport?
Carrier molecules in the plasma membrane are actually used for both active and passive transport of molecules. In active transport, carrier proteins use energy to move molecules against their concentration gradient, while in passive transport, carrier proteins facilitate the movement of molecules down their concentration gradient without the need for energy input.
When would active transport be used by a cell?
Active transport is used when molecules are moved across a cell membrane against their concentration gradient, from a low to a high concentration.
Is active or passive transport involved?
In active transport the ATP is used to pump molecules up the concentration gradient. Transport of molecules occurs from a low concentration of solute to high concentration of solute and requires cellular energy. While passive transport involves carriers, channels, or direct diffusion through a membrane.
What is used in facilitated diffusion to assist transport of sugar and sodium molecules?
transport proteins both are carrier proteins and channel proteins
What process is used to move sugar molecules across a cell membrane?
The process used to move sugar molecules across a cell membrane is called facilitated diffusion. This process involves the use of transport proteins in the cell membrane to help facilitate the movement of sugar molecules from an area of higher concentration to an area of lower concentration, without requiring energy input from the cell.
What must be used to transport materials that cannot diffuse across the membrane?
Transport proteins, such as channels and carriers, must be used to transport materials that cannot diffuse across the membrane. These proteins facilitate the movement of specific substances across the cell membrane by providing a passageway or binding site for the molecules to move through.
What small membrane-bound sac is used to transport cellular chemicals?
A small membrane-bound sac used to transport cellular chemicals is called a vesicle. Vesicles help transport molecules between different cellular compartments and play a key role in maintaining cellular organization and function.
What occurs when molecules ATP to pump molecules from one side of a membrane to the other?
ATP molecules release their third phosphate group in the reaction ATP --> ADP + P + Energy. The energy stored between the second and third phosphate groups is released and used by the cell to do work, such as pumping molecules across the cell membrane.
