Exploring Light Reactions and the Calvin Cycle

What are the two main stages of photosynthesis discussed in the video?

• Photosystem I and Photosystem II

• Light reactions and Calvin cycle

• Calvin cycle and Krebs cycle

• Light reactions and Dark reactions

What must occur for the light reactions to take place?

• Chlorophyll must be cold

• Chlorophyll must be in darkness

• Chlorophyll must be exposed to light

• Chlorophyll must be dry

What is the role of light in the light reactions?

• It synthesizes water molecules

• It breaks down glucose

• It absorbs carbon dioxide

• It provides energy to add a phosphate to ADP

What is ATP commonly referred to as in cellular activities?

• Fat molecule

• Protein molecule

• Sugar molecule

• Energy molecule

What happens to ADP during the light reactions?

• It loses a phosphate group

• It gains a phosphate group

• It remains unchanged

• It is completely broken down

Which molecule is described as a 'partially drained battery'?

• Glucose

• NADPH

• ADP

• ATP

How many phosphate groups does ATP contain?

• One

• Three

• Two

• Four

What are the products of water molecule breakdown in the light reactions?

• Oxygen, electrons, and hydrogen ions

• Glucose, oxygen, and electrons

• Hydrogen, carbon dioxide, and nitrogen

• Carbon dioxide, water, and oxygen

What does the Calvin cycle use to produce glucose?

• Water, sunlight, and chlorophyll

• ADP, oxygen, and carbon dioxide

• ATP, hydrogen ions, and free electrons

• Glucose, fructose, and electrons

What is the final product of the Calvin cycle?

• Carbon dioxide
