Photosynthesis and Respiration in Detail 22-23

Photosynthesis and Respiration Details

You will learn about the processes inside photosynthesis and cellular respiration that allow for energy conversions to take place in the organelles.

Key Metabolic Vocabulary

Some text here about the topic of discussion

• Chlorophyll - pigment that absorbs light, looks green because it reflects green light.

• NADP+ - is an empty electron carrier /energy carrier

• NADPH - an electron carrier that is full of energy

• ATP Synthase - enzyme that makes ATP

• ADP - an empty energy carrier

• ATP - an energy carrier that is full

Multiple Choice

Which of the following is the correct equation for PHOTOSYNTHESIS?

• CO₂ + light + H₂O --> O₂ + Sugar
• CO₂ + sugar + H₂O --> O₂ + light
• _O2 + light + H₂O --> CO₂ + Sugar
• CO₂ + O₂ + H₂O --> Light+ Sugar

Stomata - tiny pores or openings on leaves that allow for the exchange of gases.

​

Carbon dioxide goes in for photosynthesis

Oxygen comes out ​

Multiple Choice

If carbon dioxide is removed from a plant’s environment, what would you expect to happen to its production

of high-energy sugars?

• More sugars will be produced.
