An atom is the smallest unit of matter that cannot be broken down chemically. It consists of a nucleus made up of protons and neutrons, surrounded by a cloud of electrons:

Protons: Have a positive charge and are located in the nucleus
Neutrons: Have no charge and are located in the nucleus
Electrons: Have a negative charge and move around the nucleus

The number of protons in an atom's nucleus is called the atomic number, and it determines the atom's place on the Periodic Table. The number of neutrons in an atom determines its isotope.

Cytosolic proteins are proteins found in the cytosol, the fluid portion of a cell's cytoplasm that's not part of organelles or membranes. Some examples of cytosolic proteins include:
Hemoglobin
A protein found in erythrocytes that's critical for maintaining their function and homeostasis
α-tubulin
A cytosolic protein that's affected by TBA
Caldesmon
A protein that binds to actin, tropomyosin, calmodulin, myosin, and phospholipids
Nod1 and Nod2
A family of cytosolic proteins that regulate the host response to pathogens

Secretory proteins are proteins that are produced by cells and released into the extracellular space. They play a crucial role in cell communication, signaling, and physiological processes.
Here are some facts about secretory proteins:
Production
Secretory proteins are synthesized as precursors with signal peptides at their N-terminal ends. The signal recognition particle (SRP) recognizes the signal peptides and targets the protein to the endoplasmic reticulum (ER) membrane.
Folding
The ER ensures that the protein is folded correctly. If the protein is not folded correctly, it is exported to the cytosol and labeled for destruction.
Sugar chains
A sugar chain is added to the protein.
Transport
The protein is transported to the Golgi apparatus by a coated vesicle. In the Golgi apparatus, the sugar chains are modified.
