Which organelle helps release energy in cells?

• Chloroplast

• Mitochondria

• Nucleus

• Ribosome

Which function would the energy releasing organelle most likely have in the animal cell?

• Cellular Control

• Removal of Wastes

• Cellular Respiration

• Storage of Nutrients

Photosynthesis is a process where plants use ______ energy to create ________ and oxygen.

• chemical, food

• solar, glucose

• chemical, glucose

• solar, protein

Which statement about photosynthesis is false?

• During the process of photosynthesis matter is destroyed and energy is created.

• The process of photosynthesis converts light energy to stored chemical energy.

• The sugar molecules created during photosynthesis store the energy absorbed during photosynthesis.

• When molecules absorb energy, chemical bonds can be broken. When molecules release energy, chemical bonds can be formed.

Which reaction represents the most accurate model of how matter is transformed and conserved in photosynthesis?

• CO2 + H2O + sunlight --> O2 + C6H12O6 +CO2

• C6H12O6 + 6O2 --> 6CO2 + 6H2O + energy

• C6H12O6 + O2 --> CO2 + H2O + energy

• 6CO2 + 6H2O + sunlight --> 6O2 + C6H12O6

Depending on the environmental conditions, Euglena, a unicellular protist can act as either a produce or consumer. Euglena will most likely act as a consumer when placed in which of these environments?

• Cool

• Acidic

• Low-Oxygen

• No-light

Which organelle in Euglena cells converts solar energy into usable energy?

• Nucleus

• Ribosome

• Chloroplast

• Mitochondion

Anaerobic respiration occurs primarily in conditions where:

• excess carbon dioxide has built up

• oxygen is abundant

• carbon dioxide is not available

• oxygen is not available

The chemical process whereby the bonds of food molecules and oxygen molecules are broken and the bonds in new compounds are formed resulting in a net transfer of energy is called:

• Cellular Respiration

• Photosynthesis

• Digestion

• Absorption

Which reaction represents the most accurate model of how matter is transformed and conserved in cellular respiration?

• CO2 + H2O + sunlight --> O2 + C6H12O6 +CO2

• C6H12O6 + 6O2 --> 6CO2 + 6H2O + energy

• C6H12O6 + O2 --> CO2 + H2O + sunlight

• 6CO2 + 6H2O + sunlight --> 6O2 + C6H12O6
