Which of the following processes produces ATP?
cellular respiration
external respiration
ventilation
internal respiration
The Correct Answer is A
A. Cellular respiration: Cellular respiration (glycolysis, Krebs cycle, oxidative phosphorylation) produces ATP
B. External respiration: External respiration is gas exchange between lungs and blood, not the ATP-producing biochemical process
C. Ventilation: Ventilation (breathing) moves air in/out of lungs but does not itself synthesize ATP
D. Internal respiration: Internal respiration is gas exchange between blood and tissues, not the intracellular ATP-producing pathways

Correct Answer is A
Explanation
A. The movement of white blood cells through blood vessel walls: diapedesis (transmigration) is when leukocytes squeeze between endothelial cells to leave the bloodstream and enter tissues.
B. The formation of platelets from megakaryocytes: that process is thrombopoiesis (platelet production), not diapedesis.
C. The squeezing of red blood cells through narrow capillaries: RBCs deform to pass through capillaries, but that is not called diapedesis.
D. The filling of red blood cells with hemoglobin: hemoglobin synthesis and RBC maturation are separate processes, not diapedesis.
Correct Answer is B
Explanation
A. Hypothalamus -The hypothalamus regulates autonomic functions like temperature, but not primary breathing rhythms.
B. Pons and medulla oblongata -The medulla sets the basic rhythm of breathing, and the pons fine-tunes it.
C. Alveoli -Alveoli are sites of gas exchange, not neural control.
D. Cerebral cortex -The cortex allows voluntary control of breathing but is not the main respiratory control center.
