Answer:
C. NAD⁺
Step-by-step explanation:
NADH is oxidized to NAD⁺ in Complex I of the Electron Transport Chain.
NADH ⟶ NAD⁺ + H⁺ + 2e⁻
The electrons continue through the Electron Transport Chain, and the NAD⁺ is used in three places during the Krebs Cycle.
(a) Isocitrate to oxalosuccinate
Isocitrate + NAD⁺ ⟶ oxalosuccinate + NADH + H⁺
(b) α-Ketoglutarate to succinyl-CoA
α-ketoglutarate + NAD+ + CoA → succinyl CoA + CO₂ + NADH
(c) Malate to oxaloacetate
Malate + NAD⁺ ⟶ oxaloacetate + NADH + H⁺
The NADH produced by these three reactions can then be used by Complex I in the Electron Transport Chain.
Answer:
1) As the body's chemical messengers, <u>hormones</u> transfer information and instructions from one set of cells to another.
2) A <u>gland</u> is a group of cells that produces and secretes, or gives off, chemicals.
3) Hormones are released into the bloodstream via small tubes called <u>duct.</u>
4) Hormones find their way through the blood to their <u>targeted/respective </u>cells.
5) Each hormone is a differently shaped key that will only fit into the correct <u>receptor</u> lock.
