The correct terms to fill in the blanks are lateral ventricles and venous sinus blood. Cerebrospinal fluid (CSF) is formed by lateral ventricles and reabsorbed through arachnoid granulations into the venous sinus blood. The CSF is a fluid that is clear and colorless found in the spinal cord and in the brain, generally the central nervous system. The CSF functions as a buffer or a shock absorber for the brain. It provides basic mechanical protection for the brain. Also, it helps in the circulation of nutrients and the chemicals that are filtered and aids in the elimination of waste products.
Answer;
-NAD+
Explanation;
-When glucose breaks down into ATP, a large amount of the energy is stored as electron on special molecules (the electron carriers). When an empty electron carrier accepts a pair of electrons, it is reduced; when it gives those electrons up later on, it is oxidized.
-NAD+ and FAD; also the two most common electron carriers in the body. NAD+ can accept a pair of electrons (and a hydrogen ion) to become NADH.
