Explanation / Answer

47. The end products of glycolysis are pyruvate in aerobic condition and lactate in anerobic condition.

ans.c

48.When oxygen is absent, a cell can metabolize the pyruvates through the process of fermentation.Heterolactic fermentation proceeds in two steps.

49. The medulla in the human kidney is divided into conical masses called renal pyramids. The base of each pyramid originates at the corticomedullary border, and the apex terminates in a papilla, which lies within a minor calyx. Minor calyces collect urine from each papilla.The major calyces in turn feed into the pelvis.

50. Constriction of the afferent arteriole decreases the blood flow into the glomerulus and thus the glomerular hydrostatic pressure, which leads to a decrease in GFR.

51. The glomerulus is a tuft of small blood vessels called capillaries located within Bowman's capsule within the kidney. The glomerulus and its surrounding Bowman's capsule are called a renal corpuscle. This structure is located in the renal cortex.

52. a.Low systemic blood pressure causes decreased glomerular filtration rate and decreases urine production which leads to kidney damage.
