Number of carbon atoms in one glucose moleculeExplanation / Answer
78. (a)
The amount of water absorbed is far greater than excreted
79. (a)
Glycolysis produces 2 ATP without ( ETC) and 1 cycle of Kreb's cycle produces 1 ATP (without ETC)
80. (a) Gastric phase produces 50-60% of the gastric acid whereas the cephalic phase produces 30% only.
81.(a)
Jejunum absorbs a much greater amount of nutrients than large intestine.
82. (b)
pH of chyme in the stomach is around 1-3. In the large intestine, it is a little over 7.
83. (b)
NPF= GBHP (55) - BCOP-CHP
Hence, higher the blood colloidal osmotic pressure, lower the NPF.
84. (a)
PCT absorbs most of the water (67%). A very small % is excreted as urine.
85. (b)
When the level of ADH is high, water reabsorption increases and very less urine is produced. (vice versa)
86. (a)
Osmolarity of filtrate entering the descending limb is 300 mOsM
Osmolarity of filtrate leaving the ascending limb is 100 mOsM
87. (a)
As nutrient absorption takes place along the PCT-Lopp of Henly-DCT
the filtrate entering PCT has the highest concentration of nutrients.
88. (a)
The diameter of afferent arteriole is greater than that of efferent arteriole.
89. (b)
Renin is responsible for increasing the blood pressure. Hence systemic BP will be higher after renin secretion.
90. (a)
Glucose is 6C whereas Pyruvate is only 2C.
