question 13

Multiple Choice

What metabolic advantage do cells have in storing the elemental sulfur byproduct from sulfide oxidation?

• A) The cells avoid producing transport energy waste to secrete the sulfur.
• B) The byproduct serves as an electron reserve for subsequent oxidation.
• C) Sulfur decreases the intracellular acidification for non-acid-tolerant sulfide oxidizers.

Definitions:

Mean Arterial Pressure

The average blood pressure in an individual's arteries during one cardiac cycle, essential for ensuring effective tissue perfusion.

Peripheral Resistance

Peripheral resistance is the resistance of the arteries to blood flow. As the arteries constrict, the resistance increases and blood pressure rises.

Cardiac Output

The volume of blood pumped by the heart per minute, indicative of the heart's efficiency.

Chronic Stress

Chronic stress is a condition of prolonged emotional pressure considered beyond an individual's control.
