Question 1

Changes in arterial blood pressure at rest…

Answer 1

Although arterial pressure oscillates over time, mean arterial pressure oscillates over time, mean pressure remains constant.

Question 2

Components of a control system:

Answer 2

Sensor or receptor: detects the changes in the variable.
Control center: assesses the input and initiates response.
Effector: changed internal environment back to normal.

Question 3

Changes in body core temperature during exercise…

Answer 3

Question 4

Hormesis

Answer 4

Process in which a low-to-moderate dose of a potentially harmful stress (for example, chemical agent or environmental stress) results in a beneficial adaptive response on the cell or organ system.
Exercise-induced hormesis defines much of what we know about exercise-induced adaptation in the body.

Question 5

Anaerobic glycolysis

Answer 5

Take the H+ (from NADH), attach it to pyruvate, and make lactate.
FAST
Net = 2 ATP

Question 6

Aerobic glycolysis

Answer 6

NADH and the pyruvate does to the mitochondria and goes throw the Kreb’s Cycle and ETC.
SLOW
Net = 32 ATP
