What is the formula for Glucose ? 4 What is the formula for Glucose ? answer C6H12O6 Calderglen High School

What is STARCH and how is it made? 5 What is STARCH and how is it made? answer A complex carbohydrate Made when many Glucose molecules join together (polymerise) Calderglen High School

What is the test for Starch? 6 What is the test for Starch? answer Iodine solution turns blue/black Calderglen High School

What is the test for GLUCOSE? 7 What is the test for GLUCOSE? answer Benedict’s solution turns orange/red (when heated) Calderglen High School

Why do plants make STARCH? 8 Why do plants make STARCH? answer They make starch from glucose to store energy Calderglen High School

How is starch broken down? 9 How is starch broken down? answer Starch is broken down during digestion in the body. Calderglen High School

Which carbohydrate can pass through the gut wall into the bloodstream? 10 Which carbohydrate can pass through the gut wall into the bloodstream? answer GLUCOSE (small, soluble molecule) (starch is large and insoluble – can’t pass across gut wall) Calderglen High School

Which process breaks down glucose for energy? 11 Which process breaks down glucose for energy? answer RESPIRATION Calderglen High School

What is the word equation for respiration? 12 What is the word equation for respiration? answer glucose + oxygen  energy + carbon + water dioxide Calderglen High School

What is PHOTOSYNTHESIS? 13 What is PHOTOSYNTHESIS? answer The process by which plants make carbohydrates from carbon dioxide and water using light energy Calderglen High School

What gas is released as a by-product of photosynthesis? 14 What gas is released as a by-product of photosynthesis? answer Oxygen (O2) Calderglen High School
