Cellulose and Protein Synthesis

Glucose isn't just for energy; it's the building block for the plant's entire structure, from cell walls to complex proteins.

What mineral ion is needed to turn glucose into proteins?

What is Cellulose and Protein Synthesis?

"Cellulose is a structural carbohydrate in cell walls, and proteins are vital for growth; both are derived from glucose in plants."

Question 1

Which word equation correctly represents photosynthesis?

Question 2

On a very hot, bright day, the rate of photosynthesis might actually slow down. Why?

Question 3

Which change would usually increase the rate of photosynthesis if light intensity is the limiting factor?

Question 4

In which part of a plant cell does photosynthesis take place?

Building Molecules

Glucose is converted into cellulose for strong cell walls.

Glucose + nitrate ions are used to make amino acids for proteins.

These proteins are used for growth and enzyme production.

Exam Tip

Plants can't make proteins from glucose alone; they MUST have nitrates from the soil.

Want to improve faster?

The fastest way to improve your grade is to practise exam-style questions, identify your gaps, and focus only on what you don't know.
