Answer:
4. D (enzymes 1 and 3 works equally well in an acidic and alkaline environment respectively)
5. C. 2; 7; 9.5
Explanation:
The image attached to this question shows a graphical representation of the pH ranges for three enzymes. According to the image;
- Enzyme 1 reached its peak reaction rate at pH 2 (acidic)
- Enzyme 2 reached its peak reaction rate at pH 7 (neutral)
- Enzyme 3 reached its peak reaction rate at pH 9.5 (basic)
This result means that enzymes 1, 2 and 3 will work well and effectively at an acidic, neutral and alkaline environment respectively. Likewise, the optimal pH level for enzymes 1, 2 and 3 are 2; 7; and 9.5 respectively.
The minimum voltage is observed as the resting potential of the cell membrane. This has a value of -70 millivolts and exists when there is no stimulus present. After a stimulus is applied, the sodium-potassium channels allow the movement of ions in and out of the cell membrane. Before the channel is able to close again and restore itself to the resting potential, hyperpolarization occurs and a maximum voltage of about 30-40 millivolts is achieved. <span />
