Moderate-intensity exercise improves vagal tone better than high-intensity exercise.

What physiological markers increase with Dorsal Vagal Complex?

What type of vagal tone activates PNS and allows faster relaxation following stimulus?

Vagal tone can be measured by tracking biological process:

Which cranial nerve is the vagus nerve?

Given Bx resource Table 2 and Coenzyme Q, Cytochrome c (3+), NAD+ and O2, all of which are involved in electron transport, match the one that best satisfies each of the following properties.

Given Bx resource Table 1, the coupled reaction catalyzed by hexokinase, and its uncatalyzed half-reactions, select the answer that best describes the sign of the ∆Go’ of each. coupled reaction:    g l u cos e   +   A T P → g l u cos e ‐ 6   p h o s p h a t e   +   A D P half-reaction 1:        g l u cos e   +   P i → g l o cos e ‐ 6   p h o s p h a t e   +   H 2 O half-reaction 2:        A T P   +   H 2 O   →   A D P   +   P i

Brown adipose tissue generates heat by controlled dissipation of the proton gradient across the inner mitochondrial membrane through the mitochondrial uncoupling protein (UCP). Identify the effect on mitochondrial properties that are associated with increased uncoupling protein activity. Answer choices: Decrease Increase No change    Parameter Effect of increased uncoupling protein activity    Intermembrane space pH    Matrix pH    ATP synthase activity    ATP/ADP translocase    

Isolated mitochondria are able to sustain ATP synthesis when provided with ADP, Pi, O2, and a regenerating supply of NADH or FADH2 as the sole source of electrons for oxidative phosphorylation. Predict how inhibition of Complex I will affect O2 consumption and ATP synthesis. Answer choices: Decrease Increase No change Site of inhibition Sole source of electrons Oxygen consumption ATP synthesis Complex I NADH Complex I FADH2
