Welcome to your CIE A2 Homeostasis Which of the following is incorrect regarding the tubular selective reabsorption at the loop of Henley? Some amount of water is reabsorbed into the blood passively. When glomerular filterate flows along the ascending limb towards the distal convoluted tubule, it becomes hypertonic. The blood flows parallel and in opposite direction to the filterate which flows downwards along the descending limb. The filterate becomes hypertonic when it reaches the proper loop of Henley.Which of the following is an incorrect statement about the homeostatic control of the concentration of glucose in the blood? The liver is an effector organ in blood glucose homeostasis. The concentration of glucose in the blood fluctuates within narrow limits. The hypothalamus is the control centre for blood glucose. Negative feedback is involved in the control of blood glucose.Which type of cells line the Bowman's capsule of the kidney? Podocytes Chromaffin cells Beta cells ConesWhere are the GLUT proteins found in cells? Mitochondria Cytoplasm Nucleus Plasma membraneStomata open in response to: High temperature Low humidity Increasing light intensity DarknessWhich of the following is incorrect regarding the selective reabsorption which takes place at distal convoluted tubule? The cells of distal convoluted tubule secrete hydrogen ions and ammonium ions into the filterate actively. Reabsorption of water according to the osmotic pressure in blood is controlled by ADH. Chlorine ions are reabsorbed passively according to blood pH levels. Reabsorption of sodium ions is controlled by ADH.Which of the following factor is not regulated by the kidney? Blood pressure Blood oxygen level Blood pH value Osmotic pressure of bloodThe hole between the guard cells: Thylakoid Granum Stoma StromaWhich of the following hormones do not take part in increasing the blood glucose level when it is low? Adrenaline hormone Insulin Growth hormone Cortisol hormoneWhat is the first stage of urine formation? Tubular selective reabsorption Tubular secretion Glomerular ultra filteration Tubular secretion and tubular selective reabsorptionWhich of the following does not occur when the blood glucose level rises? Glycogen is converted into glucose. Secretion of glucagon from alpha cells is reduced. Beta cells of islets of langerhans secrete insulin. Permeability of body tissues such as liver, muscle and fat cells for glucose is increased.
