Question

In plants, glucose is derived from sucrose, which is the end product of photosynthesis or from storage carbohydrates. Sucrose is converted into glucose and fructose by the enzyme?

• A. Zymase
• B. Hexokinase
• C. Sucrase
• D. Invertase

Answer 1

The correct option is C Sucrase

In plants, sucrose is the major transport form for photo assimilated carbon and is both a source of carbon skeletons and energy for plant organs unable to perform photosynthesis (sink organs). As a molecule translocated over distance, sucrose has to pass through a number of membranes. Membrane transport of sucrose has therefore been considered for a long time as a major determinant of plant productivity. The enzyme sucrase digests sucrose its constituent units of glucose and fructose.

So the correct option is 'sucrase'.
