In a cell, breakdown usually occurs in lysosomes through various enzymes. However, this relates to cell waste, debris, etc. In terms of food breakdown, enzymes usually do this. Amylase works on starch, pepsin on proteins, and lipase on fat. Also, in a general cell model, lysosomes are usually described as the breakdown mechanism (and also crucial for apoptosis). You would need to ask about specific types of cells in order to get a good answer.
Molecules are smaller. Sub atomic particles are even smaller
LDL (low-density lipoprotein) and HDL (high-density lipoprotein) particles differ in their composition and function. LDL particles are larger and contain more cholesterol, while HDL particles are smaller and contain more protein. LDL particles transport cholesterol from the liver to cells, while HDL particles remove excess cholesterol from cells and transport it back to the liver for disposal.
Because phagocytosis in the endocytosis on solid particles, while pinocytocis is the endocytosis of liquid particles. Liquid particles can be compacted into smaller vesicles then solid particles.
A sac filled with digestive chemicals would likely belong to an organism with a type of digestive system where digestion occurs externally. Examples include certain insects like beetles and spiders that use their digestive sacs to break down and pre-digest food before consuming it. The chemicals in the sac help to breakdown food particles into smaller, more digestible components.
HDL (high-density lipoprotein) and LDL (low-density lipoprotein) particles differ in their composition and function. HDL particles are smaller and denser, with a higher protein to lipid ratio, while LDL particles are larger and less dense, with a higher lipid content. HDL is known as "good" cholesterol because it helps remove excess cholesterol from the bloodstream, while LDL is considered "bad" cholesterol because it can contribute to plaque buildup in arteries.
Water flows faster through cylinders containing large particles because there are larger spaces between the particles, allowing for less resistance to the flow of water. In contrast, cylinders containing smaller particles have more surface area and tighter packing, which creates more friction and resistance to the flow of water.
Electrons are not known to be made up of smaller particles.
Lysosomes are the organelles that release chemicals to break large food particles into small ones.
A sieve or a sieve shaker can be used to quickly separate a dry mixture containing particles of different sizes. The mixture is poured onto the sieve, which allows smaller particles to fall through while larger particles are retained on top.
amino acids formed from chemicals. DNA is a molecule, and it is a molecule containing other smaller molecules. DNA ->Nucleotides -> Amino Acids -> Chemicals.
Neutrinos are considered to be elementary particles without any internal structure (i.e., they are not believed to be composed of yet smaller and more elementary particles.)
The arrangement and number of smaller particles in an atom refers to its atomic structure. This includes the organization of protons, neutrons, and electrons within the atom and their respective quantities.
Leptons, such as electrons and neutrinos, are subatomic particles that do not respond to the strong nuclear force and are considered to have no internal structure. They are fundamental particles that are not made up of smaller components like quarks in protons and neutrons.
Subatomic particles are particles that are smaller than an atom, such as protons, neutrons, and electrons. They make up the structure of an atom and contribute to its properties and behavior. These particles are fundamental to understanding the world of particle physics.
The size of rock particles are important to soil structure because the larger particles of sand allow rainwater to drain quickly through the soil, while the smaller particles of clay prevent rapid drainage.
Mechanical weathering is the breaking of rock into smaller particles without a change in chemistry. An example would be the tumbling and rounding of a pebble in a stream.
Particle size can affect the rate of crystal formation, with smaller particles typically leading to faster crystal growth due to the increased surface area available for molecules to attach and form the crystal lattice. Additionally, smaller particles may result in finer crystals or a more homogeneous crystal structure compared to larger particles. Smaller particles can also lead to better solubility and distribution of the crystal in a solution.
