Packages that transport proteins out of the cell.

Packages that contain enzymes for breaking down waste materials within the cell.

Packages that contain components needed for the cell membrane.

The process of releasing proteins from the Golgi apparatus.

The process of modifying proteins in the Golgi apparatus.

Smooth ER plays a key role in producing certain types of lipids, particularly steroid hormones.

Steroid hormones are a type of lipid hormone. Smooth ER is involved in the synthesis of these hormones.

Testes are the male reproductive organs responsible for producing testosterone, a steroid hormone. Smooth ER is highly abundant in these cells to facilitate this process.

The adrenal gland cortex is responsible for producing steroid hormones like cortisol. This explains why smooth ER is abundant in these cells.

Smooth ER is crucial for the production of specific lipids and hormones, which play vital roles in different functions of the body.

A network of protein fibers that provides structural support for the cell and anchors organelles to specific locations.

Long, thin fibers made of actin protein, often found in bundles, that help with cell movement, shape, and division.

The process by which a cell uses the cytoskeleton to move itself or its components.

The ability of a cell to change its shape and move by extending and retracting projections.

A small, cylindrical structure composed of tubulin protein that helps move organelles, chromosomes, and other cellular components.

Chromatin is the loose, uncoiled form of DNA found in the nucleus of a non-dividing cell.

During cell division, chromatin condenses into tightly packed structures called chromosomes.

Chromosomes contain genes, which are the units of heredity.

Genes are composed of DNA, which is the blueprint of life.

DNA contains the instructions for building and maintaining an organism.

Lysosomes are small, membrane-bound sacs filled with powerful enzymes to break down waste and debris inside the cell.

The Golgi apparatus packages and modifies proteins, and then sends them off to form lysosomes.

Lysosomes contain hydrolytic enzymes, which are biocatalysts that speed up the breakdown of molecules.

Lysosomes digest worn-out cell parts, bacteria, and other debris that enter the cell.

Lysosomes help maintain the cell's health by removing unwanted materials and preventing build-up of waste.

The nucleus is the control center of the cell, responsible for directing its metabolic activities and ultimately defining its characteristics.

Nucleoli are small, dense bodies found within the nucleus. They are responsible for producing ribosomal RNA (rRNA), a crucial component of ribosomes, which are involved in protein synthesis.

Ribosomes are small organelles responsible for synthesizing proteins. They are made up of ribosomal RNA (rRNA) and proteins.

Ribosomal RNA (rRNA) is a type of RNA that is a crucial component of ribosomes.

Protein synthesis is the process by which cells create proteins. It involves the translation of genetic information from DNA into RNA and then into proteins.
