Light Dependent

Which of the following is the correct equation for PHOTOSYNTHESIS?

• CO₂ + O₂ + H₂O --> Light+ Sugar

• CO₂ + sugar + H₂O --> O₂ + light

• CO₂ + light + H₂O --> O₂ + Sugar

• _O2 + light + H₂O --> CO₂ + Sugar

Which molecule absorbs the energy of a photon in photosynthesis?

• ATP

• glucose

• chlorophyll

• water

When electrons in the reaction-center chlorophyll become so excited; they escape to a nearby __________.

• primary electron acceptor molecule

• secondary electron acceptor molecule

• chloroplast

• cellular membrane

After the excited electrons are captured by the primary electron acceptor, water is split in a process known as what?

• photosynthesis

• photolysis

• chemiosmosis

• electron transport chain

After the electron from photosystem I is transferred to the primary electron acceptor, it is passed along the electron transport chain by the carrier

• Plastoquinone

• Plantacyanin

• Cytochrome complex

• Ferredoxin

Through the NADP+ reductase, the electrons' energy are transferred from ferredoxin to NADP+, the NADP+ required energy from how many electrons so that it can be reduced into NADPH?

• 1

• 2

• 3

• 0

As the excited electrons lose energy along the electron transport chain, they are fueling the process of:

• Light capturing event

• Chemiosmosis

• Photolysis

What are the products of the light-dependent reaction?

• Glucose

• ATP and NADPH

• Water and Oxygen

Plants produce oxygen when they photosynthesize. Where does the oxygen come from?

• splitting water molecules

• ATP synthesis

• the electron transport chain

• chlorophyll

The thylakoid membrane becomes damaged, causing the inside of the thylakoid to mix with the stroma.

Which of the following processes is likely to be most affected by this damage?

• The reduction of NADP+ to NADPH

• Sunlight absorption by the chloroplasts

• The movement of electrons from photosystem II (PSII) to photosystem I (PSI)

• ATP synthesis
