How does prokaryotic cells secrete proteins?
Prokaryotic cells secrete proteins through a process called translocation. Proteins are synthesized in the cytoplasm and then moved across the cell membrane through protein channels or transport systems. Once outside the cell, the proteins can carry out various functions in the surrounding environment.
What is moved into cytoplasm?
Messenger RNA (mRNA) molecules are moved into the cytoplasm in eukaryotic cells after they are transcribed in the nucleus. This mRNA carries the genetic code from the DNA and is used by ribosomes to synthesize proteins.
What is the process by which molecules such as glucose are moved into cells along their concentration gradient with the help of membrane bound carrier proteins called?
The process by which molecules such as glucose are moved into cells along their concentration gradient with the help of membrane bound carrier proteins is called facilitated diffusion. Facilitated transport is passive and does not directly require chemical energy from ATP.
What are examples of dead cells?
Examples of dead cells include hair and nails, as they are composed of the protein keratin and do not contain any living cells. Additionally, the stratum corneum layer of the skin is made up of dead skin cells that have moved to the surface as part of the body's natural shedding process.
In what place are proteins and enzymes produced?
Proteins and enzymes are produced in the ribosomes of cells, which can be found in various organelles such as the cytoplasm and the endoplasmic reticulum. The genetic information coding for proteins is transcribed from DNA to mRNA, which is then translated into proteins by the ribosomes.

What moves proteins around cells?
Proteins are moved around cells primarily by motor proteins such as kinesins and dyneins, which utilize ATP as an energy source to transport proteins along microtubule tracks. Additionally, vesicles and membrane-enclosed compartments can also facilitate the movement of proteins within cells through processes like endocytosis and exocytosis.
What does the Golgi apparatuus do to cells?
It modifies and packages, and sorts proteins that need to be transported elswhere. After the endoplasmic reticulum creates proteins, some of the proteins may need to be transported out of the cell, or moved to a specific location. The Golgi apparatus packages proteins in the correct packages or "vescicles" and ships them off to the correct location.

What part of the body secretes mucus to trap and move dust and debris?
Goblet cells. They are located in the epithelium of many organs along with other cells. But, they are more prominent in the intestinal and the respiratory tracts.
How do the cells in a fish react when moved from saltwater to freshwater?
The cells gain water.

What is it called when vesicles are used to moved substances out of cells?
Endocytosis
Why are proteins and polysaccharides cannot be transported across a cell membrane by carrier proteins?
They are too large to be transformed by carrier proteins. They are moved across by Vesicles instead.
When is water moved from the atmosphere to earths surface?
When it rains or snows.
