4.4.1.3 Uses of Glucose from Photosynthesis

Question 1

What are some of the uses of glucose produced in photosynthesis?

Answer 1

• for respiration
• making cellulose
• making amino acids
• stored as oils or fats
• stored as starch

Question 2

How is glucose used for respiration?

Answer 2

• transfers energy from glucose
• enables plants to convert rest of glucose into various other useful substances

Question 3

How is glucose used for making cellulose?

Answer 3

• glucose is converted into cellulose for making strong plant cell walls

Question 4

How is glucose used for making amino acids?

Answer 4

• glucose is combined with nitrate ions to make amino acids, which are then made into proteins

Question 5

How is glucose used for storing oils or fats?

Answer 5

• glucose is turned into lipids for storing in seeds

Question 6

How is glucose used for storing as starch?

Answer 6

• glucose is turned into starch and stored in roots, stems and leaves, ready for use when photosynthesis isn’t happening
• starch is insoluble which makes it better for storing than glucose
• cells with lots of glucose would draw in a lot of water and swell
