motikmotik

Answer:

The correct answer will be option-D

Explanation:

The process of photosynthesis release oxygen from the plant which is used by the organism on earth during cellular respiration.

The oxygen released by the plants is formed through the splitting of water molecules as a result of the transfer of electrons through the electron transport chain in the thylakoid membrane during the light-dependent reaction.

Since the released oxygen is the result of the light-dependent reaction and not the light-independent reaction or Calvin cycle where heavy oxygen isotope is utilized in the cycle.

Thus, option-D is the correct answer.

Natali [406]

Answer:

<h2>1. Protein synthesis on attached ribosomes:</h2><h2>Destination:  cell membrane. </h2><h2>One general function : to be a surface receptor.</h2><h2>2. On free ribosomes- destination:  cytosol </h2><h2>One general function: microfilaments.</h2>

Explanation:

Proteins are synthesized by the process known as translation. Translation occurs by ribosomes as they can be attached with endoplasmic reticulum or they can be free in the cytosol.

Protein is synthesized according to the sequence of nucleotide on mRNA.

Newly synthesized protein contain signals  sequence which targets then for their final destination.

1. ONE ultimate destination of a protein produced on an attached ribosome:  These proteins, after synthesis enter into ER and then according to the signal sequence, they reach to their final destination.

Example: cell membrane.

One general function of the protein -  to be a surface receptor

2. One ultimate destination of a protein produced on a free ribosome: cytosol

One general function of the protein: microfilaments
