When the body produces glucose, for the use in cellular respiration, from
non-carbohydrate substances we refer to the process as being: - Ans--
Gluconeogenesis
What is the outcome of ketosis? - Ans--metabolic acidosis
Which of the following mechanisms produces the most ATP during cellular
respiration? - Ans--oxidative phosphorylation
Which of the following is the name of enzyme responsible for the formation
of ATP during Chemiosmosis / Electron Transport Chain? - Ans--ATP
Synthase
The goal of cellular respiration is to _______. - Ans--convert ADP
molecules into ATP molecules
Air moves out of the lungs when the pressure inside the lungs is ________. -
Ans--greater than the pressure in the atmosphere
Oxyhemoglobin dissociation is influenced by several factors, including
temperature, pH, and CO2 levels. What role does 2,3-biphosphoglycerate
(BPG) play in Oxyhemoglobin dissociation? - Ans--BPG is produced by
erythrocytes in response to high levels of glycolysis. Forces oxyhemoglobin
dissociation

following conditions must happen? - Ans--Oxygen levels must decrease
within the tissue

individual goes from a low to a high altitude because the ________. - Ans--
concentration of oxygen and/or total atmospheric pressure is lower at high
altitudes
Hypertension medicine, such as ACE Inhibitors and Angiotensin Receptor
Blockers, can do which of the following? - Ans--Reduces the severity of
COVID-19 by blocking the formation of Angiotensin II
As a gas diffuses across an air / water interface, which of the following can
be said as being true? - Ans--The pressures are equal, but not the
concentrations
