Pergunta 1: Which organelle is the main site of ATP production in a eukaryotic cell?

Resposta

The mitochondrion

Mitochondria carry out cellular respiration and host the electron transport chain, which produces most of the cell's ATP.

Pergunta 2: What is the pH of a 0.010 M solution of HCl, a strong acid?

Resposta

pH = 2.0

HCl dissociates completely, so [H⁺] = 0.010 M. Then pH = -log(0.010) = 2.0.

Pergunta 3: A 4.0 Ω resistor is connected across a 12 V battery. What current flows through the resistor?

Resposta

3.0 A

Ohm's law gives I = V/R = 12 V / 4.0 Ω = 3.0 A.
