Photosynthesis & Cellular Respiration

Our planet is bombarded continually by energy in a form not DIRECTLY useful to many organisms.  What process is responsible for converting this vast energy supply into a usable form?

• protein synthesis
• cellular respiration
• photosynthesis
• fermentation

In what form do producers store the energy that is obtained from sunlight?

• body heat
• mechanical respiration
• chemical energy
• nuclear energy

A biologist would expect an organism to be a producer if it contained

• chlorophyll
• water
• chemical energy
• organic compounds

Which is the most important energy-transfer compound in organisms?

• fat
• amino acid
• ATP
• glucose

Energy is most quickly available for all animal activities when it is in which chemical form?

• ADP
• ATP
• blood glucose
• DNA

How is a molecule of ATP different from a molecule of ADP?

• less energy
• more enzymes
• extra phosphate
• smaller molecule

An absorption spectrum for different chlorophylls shows that the light absorbed and used by plants in photosynthesis is mainly

• orange, red, green
• red, blue, violet
• blue, green, yellow
• green, yellow, orange

What is the function of the pigments in leaves?

• absorbing light for photosynthesis
• attracting pollinating insects
• storing manufactured foods
• all of the choices

The starting material needed at 1 is

• sugar
• carbon dioxide
• water
• chlorophyll

The product transferred from the light reactions to the Calvin cycle at 2, along with hydrogen (which is bound into NADPH), is

• oxygen
• chlorophyll
• water
• ATP
