USMLE - Metabolism Part 1

Glycolysis is a 10-step metabolic pathway that breaks down glucose into pyruvate, producing ATP and NADH. Key regulatory enzymes include hexokinase/glucokinase, phosphofructokinase (PFK), and pyruvate kinase. The pathway splits glucose into two molecules of G3P, which are further processed to generate energy.

NASM: Chapter 8 - Exercise Metabolism and Bioenergetics

This flashcard set defines metabolism as the sum of chemical reactions that sustain life, and introduces exercise metabolism as the study of energy processes during physical activity. It also explains substrates—the fuel sources for metabolism, such as proteins, fats, and carbohydrates—and describes carbohydrates as key energy-providing organic compounds ultimately broken down into glucose.

Para 2-3 How do you Mechanically Zero the M4 Series Weapons?
(1) Adjust the front sightpost until the base of the front sightpost is flush with the front sightpost housing. (2) Turn the elevation knob counterclockwise until the rear sight assembly rests flush with the detachable carrying handle and the 6/3 marking is aligned with the index line on the left side of the carrying handle. (3) Position the apertures so the unmarked aperture is up and the 0-200 meter aperture is down. (4) Turn the windage knob to align the index mark on the 0-200 meter aperture with the long center index line on the rear sight assembly
Para 2-4 How do you Battlesight Zero the M4 Series Weapons?
(1) Turn the elevation knob counterclockwise until the rear sight assembly rests flush with the detachable carrying handle and the 6/3 marking is aligned with the index line on the left side of the detachable carrying handle (2) Position the apertures so the unmarked aperture is up and the 0-200 meter aperture is down. (3) Turn the windage knob to align the index mark on the 0-200 meter aperture with the long center index line on the rear sight assembly.
Para 2-7 When is it only necessary to Mechanical Zero a Weapon?
Mechanically zeroing the weapon is only necessary when the weapon zero is questionable, the weapon is newly assigned to the unit, or the weapon sights have been serviced
Para 2-7 How do you mechanically zero an M16A2/A3 rifle?
(1) Adjust the front sightpost until the base of the front sightpost is flush with the front sightpost housing. (2) Turn the elevation knob counterclockwise until the rear sight assembly rests flush with the carrying handle and the 8/3 marking is aligned with the index line on the left side of the carrying handle. (3) Position the apertures so the unmarked aperture is up and the 0-200 meter aperture is down. (4) Turn the windage knob to align the index mark on the 0-200 meter aperture with the long center index line on the rear sight assembly.
Para 2-8 How do you battlesight zero an M16A2/A3 rifle?
(1) Turn the elevation knob counterclockwise until the rear sight assembly rests flush with the carrying handle and the 8/3 marking is aligned with the index line on the left side of the carrying handle. (2) Turn the elevation knob one more click clockwise. (3) Position the apertures so the unmarked aperture is up and the 0-200 meter aperture is down. (4) Turn the windage knob to align the index mark on the 0-200 meter aperture with the long center index line on the rear sight assembly.
Para 2-18 What does ARS stand for?
Adapter Rail System (ARS)
Para 2-18 Who is authorized to remove the ARS from a weapon?
Only the armorer
Para 2-18 What may the user remove only to perform preventive maintenance checks and services (PMCS)?
Only the lower assembly
Para 2-21 Why do the recoil grooves on each rail of the ARS have numbers?
1. Assist the user in remounting an accessory in the same position. 2. Allow standardization in the location of mounted accessories. 3. Identify reference points for discussions on accessory mounting locations
Para 2-21 What are the threaded ¼-inch deep holes in the ARS?
For a camera tripod adapter
Para 2-23 Which rail of the ARS will not maintain a zero with rail grabbers?
The bottom rail will not maintain zero
Para 2-29 Do all devices in a unit have to be mounted in the same location?
No; only when command directed to do so. However it should be remembered that each firer is different and may need devices differently than other Soldiers so the Command should limit directing soldiers to do so only during formal proceedings such as parades or boards but the Soldier should mark where they are zeroed with paint or grease pen
