Final answer:
The substances that will be eliminated in urine during urine formation are moved during the process of tubular secretion. This is the stage where waste products are actively secreted into the tubular fluid for elimination.
Step-by-step explanation:
The process responsible for the substances that will be eliminated in urine during urine formation is tubular secretion. During the urine formation process, three primary functions occur: glomerular filtration, which happens in the glomerulus; tubular reabsorption, which takes place in the renal tubules; and tubular secretion, occurring also in the renal tubules. Tubular reabsorption is the process in which the body reclaims water and solutes that were initially filtered out in the glomerulus. However, the substances moved through the process of tubular secretion are the waste products like metabolic wastes, urea, uric acid, and certain drugs that were not reabsorbed and are actively secreted into the tubular fluid to be eliminated in the urine. Therefore, the correct answer to the question 'All substances moved during the ___ process of urine formation will be eliminated in urine' is C. Tubular secretion.
