Answer:
Each FADH2 yields about 1.5 ATP via oxidative phosphorylation.
Explanation:
Most of the ATP molecules are produced by oxidative phosphorylation, not by substrate-level phosphorylation. During glycolysis, 2 ATP molecules per glucose are produced by substrate-level phosphorylation. Similarly, Kreb's cycle also yields 2 ATP per glucose by substrate-level phosphorylation.
For each pair of electrons transferred to O2 from FADH2 via electron transport chain, 4 and 2 protons are pumped from matrix towards the intermembrane space by complex III and complex IV respectively. It generates the proton concentration gradient required to drive the synthesis of 1.5 ATP molecules. Since oxidation of FADH2 is coupled to the phosphorylation of ADP to form ATP, the process is called oxidative phosphorylation.
Answer:
Option E, C tactile (CT) afferent
Explanation:
Whenever a slow moving gentle touch experienced, the response is due to the nerve fibers called C-Tactile afferents (CTs).
C-Tactile afferents (CTs) are unmyelinated mechanoreceptors of low threshold and low conduction velocities.
In humans, CT neurons are found in hairy skin.
The pleasant feeling observed during a slow gentle touch is due to the interaction of
CT neurons project to the insular cortex in the brain
Hence, option E is correct
The answer is C. The products contains high energy chem bonds
Answer:
C. meteorology
