Question

Cytochrome c oxidase functions in the mitochondria of most cells. What kind of ribosome makes cytochrome c oxidase?

		Free ribosome
		ER ribosome
		Neither

Copper-transporting ATPase 2 functions in the embedded in the cell membrane of epithelial cells that line the liver. What kind of ribosome makes copper-transporting ATPase 2?

		Free ribosome
		ER ribosome
		Neither

The cell enters and continues through M phase. After the microtubules fully depolymerize, the nuclear envelops fail to form around each of the two new sets of chromosomes. What phase is the cell stuck in?

		Prophase
		Metaphase
		Anaphase
		Telophase
		Cytokinesis

Answer 1

Answer 1 ) B

ER Ribosome,

Cytochrome c is mostly synthesised by the RER or Rough Endoplasmic Reticulum

Amnswer2 ) C

Neither,

It is the ATP7B gene that passes on the signal to form the copper containing ATPase enzyme which helps in the transport of cupper inside and outside of the cell and helps in excreeting excess copper into the plasma and bile in the body.

This ATP7B gene lies in the gogli network.

Answer 3) D

Telophase

It is at this stage that the nucelar membranes are formed around the cells, when it doesnt happen, it is said to be stuck in this stage.

i hope i was able to help you with the answers !:)
