Question

_____ is needed by cells to utilise oxygen and synthesis of enzymes.​

Answer 1

Explanation:

$Correct option is</p><p></p><p>C</p><p></p><p>Rough endoplasmic reticulum</p><p></p><p>Ribosomes are cell organelles, which are present in free or in bound form. They are involved in synthesis of proteins. Smooth endoplasmic reticulum is a type of endoplasmic reticulum, which does not possess ribosomes studded on its membrane.  </p><p>Golgi body has main function of modifying, sorting and packaging the proteins, which are synthesized by cells. Golgi bodies are also involved in transport of lipid molecules across the cell. The cellular secretions are also packed in vesicles formed by lysosomes and are transported out of the cell. Golgi bodies form the part of cellular endomembrane system. </p><p>Mitochondria produce the energy currency, i.e., ATP of the cell. This process is known as 'oxidative phosphorylation'. </p><p></p><p>Rough endoplasmic reticulum is a part of endoplasmic reticulum, which possess ribosomes on its surface. These are bound type of ribosomes. These are involved in the protein and enzyme synthesis. Almost all enzymes are proteins. Proteins with catalytic properties are called as enzymes.</p><p>So, the correct answer is option C.</p><p></p><p>$

Answer 2

the answer is mitochondria
