What else can I help you with?
How do proteins and polysaccharides that are too large to move into a cell through diffusion or active transport move in by?
Using endocytosis or exocytosis. A part of the plasma membrane known creates a "vesicle" around the piece of protein and brings it inside the cell. The opposite occurs during exocytosis. Think ex = exit and en = enter.
What is a ligand and how are they used to transport particles?
A ligand is a molecule that binds itself to another molecule and helps transport particles using gated channel proteins.
What is the process by which a substance is released from the cell through a vesicle that fuses with the membrane to let the substance out?
This process is called exocytosis. It involves the fusion of a vesicle containing the substance with the cell membrane, allowing the substance to be released outside the cell. Exocytosis is a vital cellular process for the secretion of molecules such as hormones, enzymes, and neurotransmitters.
What are Vesicle-mediated transport is a type of?
Vesicle-mediated transport is a type of intracellular transport where cellular materials are moved within a cell using membrane-bound vesicles. This process allows for the transport of molecules such as proteins, lipids, and other substances between different organelles within the cell or between the cell and its external environment.
How to read molecules using the symbols from the Periodic Table of Elements?
Molecules are most effectively read using structural formulas made up from symbols from the Periodic Table of Elements. These structural formulas list the atoms present in a molecule in the order that they appear in a molecule. An example is methanol, or H3COH.

What molecules move with endocytosis and exocytosis as opposed to diffusion or active transport?
Large molecules or particles such as proteins, lipids, polysaccharides, and even whole cells are typically transported through endocytosis and exocytosis, as they are too large to pass through the cell membrane via diffusion or active transport. Endocytosis brings substances into the cell by engulfing them in a vesicle, while exocytosis expels substances out of the cell by merging vesicles with the cell membrane.
What is a sentence using the word molecule?
A molecule has atleast two atoms e.g. H2O.
What happens to a cell during the exocytosis?
It reorganizes its cytoskeleton to reposition its secretory vesicles at the plasma membrane. The vesicles then fuse to the plasma membrane using a complex interaction between proteins of the vesicle membrane and proteins of the cell membrane, and a realignment of the lipids of the membranes. This creates a fusion pore, which rapidly expands to expose the vesicle contents to the extracellular milieu. This releases the vesicle contents into the extracellular space.

What is the process of recording the epididymis and seminal vesicle?
Recording the epididymis and seminal vesicle involves using medical imaging techniques such as ultrasound or magnetic resonance imaging (MRI) to visualize these structures. The images captured can then be analyzed by a radiologist or healthcare provider to assess the size, shape, and any abnormalities of the epididymis and seminal vesicle. Any findings are documented in the patient's medical records for further evaluation or treatment if necessary.
Which solute did not appear in the filtrate using any of the membranes?
The solute that did not appear in the filtrate using any of the membranes is albumin. Albumin is a large protein molecule that is too big to pass through the pores of the filtration membranes in the kidney.
What is a sentence using the word macro molecule?
A macromolecule is one that has a large number of atoms.A protein is a macromolecule.We learned about a macromolecule in class today.
Why is it difficult to scoop a molecule of sucrose with a teaspoon?
A molecule of sucrose is extremely small in comparison to a teaspoon. When trying to manipulate a single molecule of sucrose using a teaspoon, even air currents moving between the molecule and the spoon would make the sucrose molecule unwieldy.
What transport of substances from the outside to the inside of a cell by a vesicle called?
The process of transporting substances from the outside to the inside of a cell using a vesicle is called endocytosis. Endocytosis includes phagocytosis (engulfing solid particles), pinocytosis (engulfing liquid or small particles), and receptor-mediated endocytosis (specific molecules binding to receptors on the cell membrane).
What are the steps involved in exocytosis?
It reorganizes its cytoskeleton to reposition its secretory vesicles at the plasma membrane. The vesicles then fuse to the plasma membrane using a complex interaction between proteins of the vesicle membrane and proteins of the cell membrane, and a realignment of the lipids of the membranes. This creates a fusion pore, which rapidly expands to expose the vesicle contents to the extracellular milieu. This releases the vesicle contents into the extracellular space.
