rusak2 [61]

Answer:

B) Polymerases can only synthesize in the 5' to 3' direction

Explanation:

The leading strand's directionality is 3' to 5', so polymerase has no problem with replicating this one. But the lagging strand has the opposite directionality, so the polymerase must work in the opposite direction of the replication fork.In consequence, the replication process undergoes periodic breaks, and the enzymes have to stop and start again while helicase separates both strands, resulting in the polymerization of okazaki fragments.

It uses oxygen as a reactant.

It makes ATP.

It happens in the mitochondria.

Explanation:

It occurs in cells.  - this is false. Both cellular respiration and photosynthesis occur in cells.

It uses glucose as a reactant.  - this is true. Cellular respiration uses glucose as a reactant, it is broken down to release energy. Photosynthesis produces glucose.

It uses oxygen as a reactant.  - this is true. Cellular respiration uses oxygen as a reactant. In contrast, photosynthesis releases oxygen as a byproduct

It makes ATP. - this is true. Cellular respiration makes ATP. Photosynthesis uses energy to produce the sugar which is used in cellular respiration to synthesise ATP.

It happens in the chloroplasts.  - this is false. Photosynthesis occurs in the chloroplasts, not cellular respiration

It happens in the mitochondria.  - this is true. Respiration occurs in the mitochondria, whereas photosynthesis occurs in the chloroplasts.

It involves oxygen, glucose, carbon dioxide, and water. - this is false, Both photosynthesis and cellular respiration involve oxygen, glucose, carbon dioxide, and water. Photosynthesis produces oxygen and glucose using carbon dioxide and water. Respiration produces glucose and carbon dioxide using water and carbon dioxide.
