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