Question

are the sites of protein synthesis. peroxisomes golgi apparatuses mitochondria ribosomes microfilaments part g which of these manufactures cellular membranes by adding membrane proteins and phospholipids to its own membrane? ribosomes lysosomes golgi apparatus nucleolus rough endoplasmic reticulum

Explanation:

• For the first question, ribosomes are the sites where proteins are synthesized from amino - acids using mRNA as a template. Peroxisomes are involved in breaking down fatty acids and detoxifying hydrogen peroxide. Golgi apparatuses modify, sort, and package proteins and lipids. Mitochondria are the power - houses of the cell for ATP production. Microfilaments are part of the cytoskeleton for cell shape and movement.
• For the second question, the rough endoplasmic reticulum synthesizes proteins (with the help of ribosomes attached to it) and also manufactures cellular membranes by adding membrane proteins and phospholipids to its own membrane. Ribosomes are for protein synthesis only. Lysosomes contain digestive enzymes. Golgi apparatus modifies and packages substances. Nucleolus is involved in ribosome synthesis.

Answer:

• First question: D. Ribosomes
• Second question: E. rough endoplasmic reticulum
