Practice AP: Respiration and Photosynthesis

Chlorophyll appears to be green because...

• it absorbs green light

• it reflects green light

the goal of the light dependent stage of photosynthesis is to convert light energy into...

• ATP & NADPH

• glucose

• G3P

• oxygen gas

in the calvin cycle, carbon from CO₂ is incorporated to

• RuBP

• PGA

• G3P

• glucose

Where is water made in photosynthesis?

• In the light dependent reactions

• In the Calvin Cycle

• water is not made in photosynthesis

The light dependent reactions occur in the

• stroma

• thylakoid

The Calvin Cycle occurs in the

• stroma

• thylakoid

Oxygen gas is produced...

• When the water molecule is split

• During ATP synthesis

• When CO₂ is fixed in the Calvin Cycle

• What NADP+ is reduced to NADPH

A. Photons excite the electrons of PS I

B. Photons excite the electrons of PSII

C. Electrons travel along the ETC, allowing for the pumping of a proton

D. NADP + is reduced to NADPH

What is correct sequence of events?

• A, C, B, D

• B, C, A, D

• A, B, C, D

• C, A, B, D

Most plants contain more than one type of pigment. Why?

• To maximize the wavelengths of light then can absorb

• To protect their chloroplasts from unabsorbed light energy

• to allow them to do photorespiration

• to increase the number of photosystems available to them

The splitting of carbon dioxide to form oxygen gas and carbon compounds occurs during ______

• photosynthesis

• respiration

• neither photosynthesis or respiration

• both photosynthesis and respiration
