Imagine a protein that functions in the ERbut requires modification in the Golgi apparatus beforeit can achieve that function. Describe the protein’s paththrough the cell, starting with the mRNA molecule thatspecifies the protein.

The production of mRNA takes place within the nucleus, which then gets passed via a nuclear pore and gets combined with a ribosome that further takes part in the process of translation. The ribosome is attached to the rough endoplasmic reticulum. The production of protein takes place within the lumen of the endoplasmic reticulum and also gets modified there.  

With the assistance of a transport vesicle, the protein is further transported to the Golgi apparatus. The protein further gets modified within the Golgi and is carried back to the endoplasmic reticulum with the assistance of a transport vesicle, here it does all its cellular activities.  

interphase

the period of cell growth when the cell synthesizes new molecules and organelles. the cell is not dividing and it constitutes the majority of the time spent in the cell cycle

prophase

changes occur in the nucleus and cytoplasm. the chromatin condenses to form structures (sister chromatids) visible with a light microscope and the mitotic spindle begins to form, but the nucleus is still in tact

prometaphase

the nuclear envelope fragments and the spindle microtubules attach to the kinetochores of the sister chromatids

metaphase

all the cell's duplicated chromosomes are lined up at an imaginary plane equidistant between the poles of the mitotic spindle

anaphase

begins when sister chromatids separate from each other and ending when a complete set of daughter chromosomes arrives at each of the two poles of the cell

telophase

the daughter nuclei form at the two poles of a cell

cytokinesis

the division of a cytoplasm to form two separate daughter cells. usually occurs during telophase during mitosis. this and mitosis make up to mitotic (m) phase of the cell cycle

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
