Dark reactions does'nt need light. Instead, dark reactions use ATP (Adenosine Triphosphate) and NADPH ( Nicotinamide Adenine Dinucleotide Phosphate) to produce energy molecules.

Light reactions need light to produce organic energy molecules ATP and NADPH.

Answer:

c. Cerebrum

Explanation:

The cerebrum is the part of the brain that is responsible for processing the sensory information, critical thinking and learning. It stores this information and processing centers make predictions for various conditions. The Wernicke’s area and Broca’s area represent the areas of language present in the cerebral cortex and are associated with language and speech.

Elanso [62]

Answer:

Release of electrons from reducing powers to O2 via four protein complexes allows release of small amount of energy at each step and makes the process energy efficient.

Explanation:

If NADH and FADH2 would reduce O2 directly, a large amount of energy would have been released in a single step. On the other hand, oxidation of these reducing powers through a series of electron carrier release a small amount of energy at each step which in turn is temporarily stored in form of proton motive force across the inner mitochondrial membrane.

Transfer of a pair of the electron to O2 pumps four protons by complex I, four by complex III and two by complex IV. The resultant proton motive force effectively stores the energy of electron transfer. This energy is then used to drive ATP synthesis.
