Answer: Sympathetic Nervous System.
Explanation:
The sympathetic nervous system is part of the autonomic nervous system. The sympathetic nervous system activates what is often termed the fight or flight response. The sympathetic nervous system directs the body's rapid involuntary response to dangerous or stressful situations. A flash flood of hormones boosts the body's alertness and heart rate, sending extra blood to the muscles. Breathing quickens, delivering fresh oxygen to the brain, and an infusion of glucose is shot into the bloodstream for a quick energy boost. The sympathetic nervous system allows animals to make quick internal adjustments and react without having to think about it.
Answer:
CO2 increases the affinity of oxygen for hemoglobin so that hemoglobin binds oxygen more strongly
Explanation:
Hemoglobin (Hb) is a protein found in red blood cells that functions to transport oxygen (O2) to the tissues. This protein has four subunits and each subunit binds to a heme group. Each heme group in Hb contains an iron atom that binds to one O2 molecule. The affinity of hemoglobin for O2 is a critical mechanism that is dependent on the ability of Hb to carry O2 molecules. Hb is fully saturated with O2 when all of its four O2-binding sites are occupied. Moreoever, the O2-hemoglobin dissociation curve is a plot of saturation of Hb regarding the partial pressure of O2 (PO2). A rightward shift in the curve indicates that Hb has a decreased affinity for O2, while a leftward shift in the curve indicates that Hb has an increased affinity for O2. As CO2 concentration increases, hemoglobin's affinity for O2 decreases, thereby Hb binds to O2 less tightly at heme group sites and therefore the dissociation curve shifts to the right.
Answer:Without leaves green plants could not live.
Explanation:because from leaves a plant take breath or do respiration. In leaves of plants there are small pores or stomata from where they breathe. So if we can't breathe we can't live.so,Without leaves green plants could not live.
PH changes protein structure if the pH level is below seven which is acidic and or above seven which is basic. The best condition for the enzyme to work is the pH of seven this is where the protein carries out its function and is not denatured. It fits into the enzyme
