Answer:
2.47 M
Explanation:
Molarity is (mol of solute)/(L of solvent). To find molarity, convert grams of NaCl to moles of NaCl and milliliters of water to liters of water.
72.3 g ÷ 58.44 g/mol = 1.2372... mol
500 mL ÷ 1000 mL = 0.5 L
Molarity = 1.2372/0.5 = 2.47 M

Explanation:
Answers are:
Catabolism:
- g<span>enerally exergonic (spontaneous): In this reactions energy is released.
- </span><span>convert NAD+ to NADH. Electrons and protons released in reactions are attached to NAD+.
- </span><span>generation of ATP. ATP is synthesis from ADP.
- </span><span>convert large compounds to smaller compounds. Foe example starch to monosaccaharides.
Anabolism:
</span><span>- convert NADPH to NADP+. Protons and electrons are used to make chemical bonds.
</span>- <span>convert small compounds to larger compounds.</span>
