The particles that make up matter are the atoms.

Atoms do not change during a chemical change. They do not either during a physical change.

During a chemical change molecules change but not the atoms. The atoms separate from the original molecules and form new molecules. Then moleculas change but atoms remain being the same before and after the chemical change.

For example, atoms of oxygen in molecules of O2 combine with atoms of hydrogen in molecules of H2 and they form the molecules of water H2O.

The atoms of O in O2 are the same atoms of O in H2O and the atoms of H in H2 are the same atoms of H in H2O. The molecules changed, from H2 and O2 to H2O, but the atoms are the same.

Y_Kistochka [10]

Answer:

The correct answer will be option-C

Explanation:

Endoplasmic reticulum and the Golgi apparatus are the organelles where the post-translational modifications of proteins take place like folding of proteins.

Sometimes few proteins fail to fold properly and are a waste to the cell so has to de degraded. The misfolded proteins move from the endoplasmic reticulum to the cytosol through a process called "Protein dislocation".

Although the process is not properly misunderstood the protein degradation in the cytosol take place through deglycosylation and proteasomal ubiquitination.

Thus, Option-C is the correct answer.

Match the following carbohydrate molecules with the class of molecule that they belong to:

Vlad [161]

(I) Glucose; is C
(II) Starch; A
(III) Sucrose B

A) Polysaccharides
B) Disaccharides
C) Monosaccharides

Monosaccharide, disaccharides, and polysaccharides are the three major categories of molecules in Carbohydrates. 

Monosaccharides, known as simple sugar, is the simplest form of carbohydrates. Its basic molecular formula is CH2O. Monosaccharides are glucose, fructose, and galactose. Its primary function is to be the source of energy of living organisms. It is also the primary requirement for the formation of disaccharides and polysaccharides.

Disaccharides are formed when two monosaccharides are bonded together through a covalent bond. Common Dissaccharides are sucrose (glucose+fructose) or table sugar, maltose (glucose+glucose), and lactose (glucose+galactose). Its primary function is to provide nutrition for monosaccharides. Sugar in food is mostly dissaccharides.

Polysaccharides are formed when another monosaccharides is bonded to the disaccharides. This bond is called glycosidic bond. Two major polysaccharides are starch and glycogen. Starch is made by plants while glycogen is made by animals. Polysaccharides' major function is to immediately release energy from its storage. When glucose is consumed, some of them are stored and will only be released when the body needs it to satisfy the body's immediate need of energy.
