Metabolism
This molecule is the final electron acceptor in the electron transport chain.
What is oxygen (O2)?
This law states that total pressure equals the sum of partial pressures of each gas.
What is Dalton's law?
These animals maintain a constant internal osmotic pressure even when the environment changes.
What is osmoregulators?
This enzyme breaks down proteins in the stomach.
What is pepsin?
This hormone from the anterior pituitary stimulates Leydig cells to produce testosterone.
What is LH (luteinizing hormone)?
This process occurs in the cytosol and breaks down glucose into pyruvate with a net gain of 2 ATP.
What is glycolysis?
This curve shows the relationship between PO2 and hemoglobin saturation.
What is the oxygen dissociation curve?
This process in the kidney forms the initial filtrate from blood plasma.
What is glomerular filtration?
These molecules emulsify fats before digestion by lipase.
What are bile salts?
This hormone from Sertoli cells can inhibits FSH release.
What is inhibin?
This type of ATP production uses energy from electron transport and a proton gradient.
What is oxidative phosphorylation?
In capillaries, this force pushes fluid out, while oncotic pressure draws fluid in.
What are Starling force (hydrostatic and osmotic pressures)?
This mechanism in the loop of Henle helps produce concentrated urine.
What is countercurrent multiplication?
Fermentation produces short-chain fatty acids used as an energy source in herbivores.
What are volatile fatty acids (VFAs)?
The full name of the hormone axis regulating stress and cortisol production.
What is the HPA axis (hypothalamic-pituitary-adrenal)?
The total number of ATP molecules produced per glucose molecule during aerobic respiration.
What is 29-32 ATP?
An increase in CO2, H+, or temperature shifts the O2 dissociation curve to the right.
What is the Bohr effect?
This hormone increases water reabsorption in the kidney by inserting aquaporins in the collecting ducts.
What is ADH (antidiuretic hormone)?
The three major digestive enzymes for carbohydrates.
What are amylase, maltase and sucrase?
The peptide hormone lowers blood glucose by stimulating cellular glucose uptake.
What is insulin?
The end product of anaerobic glycolysis in animals.
What is lactate?
Insects use this system for direct gas transport to tissues without involving blood.
What is the tracheal system?
This hormone system increases blood pressure by vasoconstriction and Na+ retention.
What is the RAAS (renin-angiotensin-aldosterone system-m)?
"Form follows function" best describes this adaptive feature in animals related to food intake.
What is feeding structure diversity?
This hormone increases Na+ reabsorption and K+ excretion, raising blood pressure.
What is aldosterone?
