<span>Bio-indicators are macro-invertebrates that detect Water Quality based on how tolerant they are to pollution. The number of species of each type of Bio-indicator (pollution tolerant, intolerant, and semi-tolerant) will calculate the index of the water.</span>
Taking it
before exercise may stop the symptoms before they come. Albuterol is a bronchodilator that relaxes
muscles in the airways and increases air flow to the lungs. Albuterol inhalation is used to treat or
prevent bronchospasm in people with reversible obstructive airway disease. It
is also used to prevent exercise-induced bronchospasm.
Oxygen is required for aerobic respiration. This reaction produces ATP (universal currency for energy) which our bodies use to survive. Without oxygen much less ATP is produced, as aerobic respiration cannot occur in the lack of oxygen. ATP can be formed by anaerobic respiration, in the lack of oxygen, but this produces far far fewer molecules of ATP. This also produces lactic acid causing us to become fatigued and tired. Thus oxygen is crucial to produce the maximum amount of ATP possible.
Glucose is the main molecule which is respired by our bodies to produce ATP/ energy, which our bodies use to survive. Oxygen and glucose react in the mitochondria to make ATP (release energy.) It therefore, is called a respiratory substrate.
Note: I'm avoided talking about the exact phases of respiration as it is usually not covered till college/ A level standards. If you would like to know exactly which reaction requires oxygen and how it's used (i.e. the stages of respiration) don't hesitate to ask.
A b or d that’s the answer i think idek
and is prevented in the absence of , which causes calcium to trigger contraction through a response with regulatory proteins.
and filaments of the fibrils glide into one another as a result of calcium diffusing in the cytoplasm, resulting in the of the complete muscle fiber. The SERCAs pump (Sarcoplasmic/endoplasmic reticulum calcium ATPase) actively pumps ions back into the sarcoplasmic reticulum when the action potential decays.
