Complete question: Normally, concentrations of metabolically important substances, such as glucose, are

(a). high in glomerular filtrate but only a trace in urine.

(b). low in glomerular filtrate but high in urine.

(c). high in both glomerular filtrate and urine.

(d). low in both glomerular filtrate and urine.

(e). excluded from entering the excretory system altogether.

Normally, concentrations of metabolically important substances, such as glucose, are high in glomerular filtrate but only a trace in urine. Option (A)

Explanation:

The blood is filtered across the capillary walls of the glomerulus through the glomerular filtration barrier, which yields its filtrate of water and soluble substances to a cup-like sac known as Bowman's capsule. The glomerular filtrate contains a lot of water, but also important molecules like glucose, amino acids, salts and excretory material, urea in trace quantities.
