Answer:

B. Multiple origins of replication are activated per chromosome.

Explanation:

DNA replication runs in 2 directions (bidirectional), starting at the origin of replication an moving in both directions from that point. A eukaryotic chromosome may be replicating at many points along its length at any one time.

DNA is always copied in a 5´ ⇒ 3´ direction, this makes the lagging strand to be synthesized discontinuously as short okazaki fragments.

The whole process happens at the same time in both strands in a replication fork. DNA may have different replication forks at the same time to speed up the process.

In photosynthesis, the movement of protons from the stroma to the thylakoid lumen is _______ and is coupled to ________.
insens350 [35]

In photosynthesis, the movement of protons from the stroma to the thylakoid lumen is proton gradient and is coupled to<u> transfer of </u><u>protons</u>.

Protons are transported across the thylakoid membrane and into the lumen through the electron transport chain (the space inside the thylakoid disk). Protons are simultaneously removed from the stroma by reduction of NADPH and added to the lumen via water splitting (the space outside the thylakoids). Protons are pumped from the stroma to the thylakoid lumen as a result of the electron passing through the first link in the electron transport chain. A fourth protein complex in the thylakoid membrane, ATP synthase, then uses the energy stored in this proton gradient to produce ATP. This protein complex, like the mitochondrial enzyme, links proton flow back across the membrane to the creation of ATP.
