Which of the following best explains why glucose uptake into liver cells continues in insulin-resistant states, even when skeletal muscle glucose uptake is impaired?

#Unit 7. System Physiology – Animal
  1. Liver cells express GLUT-4 transporters, which are activated by AMP-activated protein kinase (AMPK) during fasting.
  2. Liver cells use GLUT-2 transporters, which are insulin-dependent and respond to glucokinase activation.
  3. Liver cells express GLUT-2 transporters, which are insulin-independent and facilitate passive glucose uptake based on concentration gradient.
  4. Glucokinase in liver cells directly increases the number of GLUT-4 transporters in the plasma membrane, enhancing glucose uptake.

Choose correct statement about Electrocardiogram Augmented Limb Leads.
a. In this type of limb lead system, two of the limbs are connected through the positive terminal of the electrocardiograph, and the third limb is connected to the negative terminal. 
b. In this type of limb lead system, two of the limbs are connected through the negative terminal of the electrocardiograph, and the third limb is connected to the positive terminal. 
c. When the positive terminal is on the right arm, the lead is known as the aVR lead; when on the left arm, it is known as the aVL lead; and when on the left leg, it is known as the aVF lead.
d. When the negative terminal is on the right arm, the lead is known as the aVR lead; when on the left arm, it is known as the aVL lead; and when on the left leg, it is known as the aVF lead.
