Nori. The black seaweed wrappers used in makimono are called nori (海苔). Nori is a type of algae, traditionally cultivated in the harbors of Japan. Originally, algae was scraped from dock pilings, rolled out into thin, edible sheets, and dried in the sun, in a process similar to making rice paper.

How would someone measure the effect of pH on the rate<br> ofenzyme reaction?
wlad13 [49]

Answer:

It can be determined by measuring product appearance or reagent disappearance also enzymatic activity (described below )

Explanation:

Effect of pH on enzymatic activity

PH effect: affects the state of dissociation of the groups, although all proteins are not affected in the same way because some do not have dissociable groups. Most enzymes have an optimal pH. If there are small changes in pH, the enzyme is not denatured. The pH can affect in two ways:

The substrate binding is better or worse than before.

That affects the catalytic speed of the reaction.

The enzymatic speed is measured in M ​​/ t and the enzymatic activity in mol / t, and the international unit μmol / min, amount of enzyme that transforms a micromol from substrate into product in one minute under optimal conditions. Another unit is the enzymatic amount that is required to transform 1 mol / s and is called katal.

Data clusters are sets of signs or symptoms that are grouped together logically. Match each sign or symptom with its appropriate
aivan3 [116]

Answer:

Explanation:

(A) PaO₂ below normal: PaO₂ is used to describe the partial pressure of oxygen dissolved in the blood. When it is below normal, it indicates the individual isn't getting enough oxygen hence there is low pressure of dissolved oxygen in the blood. This sign/symptom falls under the Respiratory/oxygenation data cluster.

(B) Dyspnea on exertion: Dyspnea is a term used to describe shortness of breath while dyspnea on exertion is when an individual runs out of breath as a result of not been able to breath deeply/properly during or after an exercise. This sign/symptom also falls under the Respiration/oxygenation data cluster.

(C) Productive cough: This is a type of cough that produces/forces mucus out of the airway (thereby clearing the airway). This sign/symptom from this description is also Respiratory/oxygenation data cluster.

(D) Oxygenation saturation 92%: Oxygen saturation is when the body can supply enough oxygen to the cells and tissues within it's system. This sign/symptom is also a Respiratory/oxygenation data cluster.

(E) Feels "too tired to do much": This can also be referred to as fatigue. This is usually as a result of inadequate energy produced (usually from glycolysis) in the body. This sign/symptom, from this description, is a Reduced energy level data cluster.

(F) Requires frequent rest periods: This usually occurs as a result of imbalance in the body's metabolism. Here, the body uses more energy than it produces; more anabolic processes (energy requiring) than catabolic processes (energy produced/released). This sign/symptom, from this description, is a Reduced energy level data cluster.
