Interpretation:
Complete the given digestion reaction and where in the
Concept Introduction:
Lactose: It is the sugar it contains in milk, our bodies use an enzyme called lactose to break down that sugar so we can absorbed in into our bodies.
Important of digestion: It is an important process that break down the proteins, fats, carbohydrate, vitamins, minerals into simpler forms so that it can absorbed easily into body cells. During this process proteins are converted into amino acids, carbohydrates are converted into simple sugars and fats are broken down into fatty acid and glycerol.

- The urea cycle can be summarized through the following reaction: O || H₂N-C-OPO3= COO- | H3N-CHCH₂COO- O || H₂N-C-NH2 + -OOCCH = CHCOO- 1. Write the reactions, using structural formulas that lead to the formation of carbamoyl phosphate and its subsequent incorporation into the urea cycle. Name the enzymes and how they are activated.arrow_forwardThe urea cycle can be summarized through the following reaction: O || H2N-C-OPO3 + COO- | H3N-CHCH₂COO b. O || H2N-C-NH2 1a Write the reactions, using structural formulas that lead to the formation of carbamoyl phosphate and its subsequent incorporation into the urea cycle. Name the enzymes and how they are activated. 1 + OOCCH=CHCOO- Write the rest of the reactions that constitute the urea cycle using structural formulas. Name the enzymes that catalyze each reaction. Indicate which reactions occur in the mitochondrion and which occur in the cytoplasm.arrow_forwardConsider the total breakdown of the glycogen structure below. Assuming each glycosidic linkage can be broken down completely and the resulting products are fed through glycolytic metabolism. a) If this molecule was in your muscles, how many molecules of ATP would it generate through fermentation? how many molecules of lactate? b) If the same molecule was in your liver, but was instead fueling glycolysis in your brain, how many molecules of ATP would it generate for the brain through glycolysis? c) The lactate produced in (a) is then transported back to the liver from your muscles. There, it can be used to drive glucose synthesis (known as the Cori cycle). Assume all glucose from this lactate is then re-incorporated into newly synthesized glycogen. List the steps needed for this transformation in the liver and the amount of ATP equivalents it will consume (going from lactate). Also, identify a signaling pathway that would trigger its incorporation into new glycogen, instead of being…arrow_forward
