Biology · Respiration in Plants

In plants, sucrose derived from photosynthesis or storage carbohydrates is converted into the monosaccharides that enter glycolysis. Which enzyme catalyzes this conversion, and what are the products formed?

1. A
   Maltase; producing two molecules of \( \alpha \)-D-glucose.
2. B
   Invertase; producing one molecule of glucose and one molecule of fructose.
3. C
   Hexokinase; producing glucose-6-phosphate and fructose-6-phosphate directly.
4. D
   Zymase; producing pyruvic acid and ethanol.
