Aminolevulinate dehydratase (ALAD ) is an enzyme that relies on zinc as a coenzyme. A zinc ion binds to the ALAD active site, wh
slavikrds [6]

Answer:

The correct option is C. It changes the three-dimensional structure of the active site so that ALAD is no longer compatible with its substrate.

Explanation:

Co-factors are molecules that are required by an enzyme to perform its function of catalysis. If a wrong co-factor binds to the enzyme then it will change the three-dimensional structure of the enzyme and the substrate will no longer fit into the enzyme. Hence, Option C is the best choice that explains the inhibition of ALAD.

Other options are false because :

Option A: The wrong co factor will not affect the substrate nor will it make it compatible for ALAD's active site.

Option B:  The wrong factor doesn't change the amino acid sequence of the protein or enzyme, rather it changes the three dimensional structure of the enzyme.

Option D : The wrong co factor won't allow the reaction to proceed at a faster rate, rather it will inhibit the reaction.

Describe the effect that exercise has on tidal volume, alveolar ventilation, and anatomical dead space compared to the resting r
gladu [14]
Exercise or any other physical activity, increases the oxygen demand in the lungs and affects the flow of air into the lungs.

Tidal Volume: The amount of air inspired (air that leaves or enters the lungs) during breathing is called tidal volume.  With the increase in physical activity such as exercise, the tidal volume increases to allow more gaseous exchange. During exercise, the amount of air to be inhaled increases, thus the tidal volume also increases.

Alveolar Ventilation: It is also known as alveolar volume. It is the amount of air that enters the alveoli in one minute. Alveolar ventilation also increases with the increase in the vital volume due to exercise. This is because oxygen demand increases during exercise.

Anatomical Dead Space: It refers to the air that is directed towards the alveoli but does not participate in the gaseous exchange It decreases during exercise due to increase in ventilation.

Life sciences about gaseous exchange please help.​
dem82 [27]

Gaseous exchange is fundamental in aerobic organisms because oxygen is required to carry out cellular respiration.

<h3>What is cellular respiration?</h3>

Cellular respiration is a series of chemical reactions by which aerobic organisms interchange oxygen and carbon dioxide with their surrounding environment.

During cellular respiration, oxygen is consumed to generate ATP and carbon dioxide is released.

In conclusion, gaseous exchange is fundamental in aerobic organisms because oxygen is required to carry out cellular respiration.
