All proteins are synthesized by ribosomes in the cell. Some ribosomes float freely in the cytosol, while others are bound to the surface of the endoplasmic reticulum. Most proteins made by free ribosomes function in the cytosol. Proteins made by bound ribosomes either function within the endomembrane system or pass through it and are secreted from the cell. Which of the following proteins are synthesized by bound ribosomes?
Select all that apply.1. actin2. ER protein3. ribosomal protein4. insulin5. DNA polymerase6. lysosomal enzyme

From the options The proteins that are synthesized by bound ribosomes are :

Lysosomal enzymes breakdown macromolecules taken up by organisms during the process of endocytosis, it is also membrane bound and it is synthesized by bound ribosomes.

Insulin helps in the regulation of the blood sugar levels by allowing the appropriate percentage of glucose in the blood to enter the body cells which provides the body with the necessary energy.

ER ( endoplasmic reticulum protein ) is responsible for the production of protein required by the body cells to function properly.

Hence we can conclude that the proteins synthesized by bound ribosomes are : lysosomal enzyme, Insulin and ER protein.

answer: i say it foxes

explanation:

you need to give us the answer options to for me to offical decide.

answer: - few nutrients

high pressure

low temperatures

explanation: 1. few nutrients:   open-ocean zone is located way far from the land, which is the main source of the essential nutrients.2. high pressure: pressure increases by 1 atmosphere for every 10 meters increase in depth.3. ample sunlight: a large fraction of the sunlight is reflected back to the atmosphere from the sea surface. 4. varying salinity: below the thermocline, the water is isolated from the atmosphere so the salinity remains stable over the year.5. low temperatures:   the temperature of open-ocean zone ranges from a low of -2°c to an average of 17°c
