<span>Glucose is the human body's key source of energy as it provides energy to all the cells in our body. Glucose also is critical in the production of proteins, lipid metabolism and is a precursor for vitamin C production.</span><span><span>Glucose is the sole source of fuel to create energy for all brain and red blood cells.</span> The availability of glucose influences many psychological processes. When glucose levels are low, psychological processes requiring mental effort l(self-control, critical thinking and decision-making) become impaired.

Answer:
Looking at tibetan highlanders who thrive at high altitudes- normally that would make us sick- they have adapted, 60% oxygen- could pose huge health issue (live with 10% less oxygen in blood than us)
Explanation:
Evolutionary adaptations- involve a change in the genetic makeup to help individuals survive in environment. Tibetans have adaptations to let them function at high altitudes
Answer:
sympathetic stimulation
Explanation:
Under stress or emergency conditions, the preganglionic neurons of the sympathetic division release acetylcholine. Acetylcholine stimulates secretion and release of epinephrine and norepinephrine from the adrenal medulla. These hormones enhance the effects of the sympathetic division of the autonomic nervous system (ANS) during stress. Epinephrine and norepinephrine augment the fight-or-flight response as they increase the heart rate and force of contraction, the output of the heart, and blood pressure. They also increase blood supply to the heart, liver, and adipose tissue. The airways to lungs become dilated and there are increase blood levels of glucose and fatty acids.
Answer:
When carbohydrate consumption exceeds the body's immediate needs for energy, glycogenesis decreases.
The process of conversation of stored glycogen in the liver and muscles to glucose is Glycogenesis. It takes place when the blood glucose drops,below certain levels and the body cells need glucose for biochemical activities.Therefore, when there are excess CHO consumption,more glucose would be in the blood,and thus no need for glycogenesis.(breakdown of glycogen)
Glycogen storage space in the liver and muscles is limited. When glycogen stores are full, use of glucose for energy __Increases__________ and oxidation of fat for energy ___decreases_________ .
Definitely, this is a simple logic.As the storage for glycogen is limited,excess glucose move into the blood, since they can not be converted to glycogen.The glucose is expended through cellular reduce the amount in the blood. Therefore, Gluconeogenesis, the production of glucose from non-CHO substances drops. Hence beta- oxidation drops.
Overall, when carbohydrate intake is excessive, lipogenesis increases.The process of converting excess CHO to fatty acids.Biochemically it is the process of converting the Carbon precursor of acetyl co -A to fatty acids.Therefore this increases to synthesized more fatty acids from CHO
