Cellular Respiration Review

What is the main goal of cell respiration?

• to break down glucose in the form of ATP

• to make ATP that we use for energy

• to create CO2 for plants

• Respiration is a byproduct of photosynthesis

Which organelle does cellular respiration occur in?

• Nucleus

• Mitochondria

• Chloroplast

• Cytoplasm

Organic compounds are used as building blocks for

• water, DNA, and starches

• water, proteins, and oxygen

• proteins, DNA, and carbon dioxide

• proteins, starches, and fats

During the process of cellular respiration, energy is released from

• carbon dioxide

• water molecules

• oxygen atoms

• chemical bonds

The energy used to obtain, transfer, and transport materials within an organism comes directly from

• ATP

• DNA

• sunlight

• starch

The diagram represents a cell organelle involved in the transfer of energy from organic compounds.

The arrows in the diagram could represent the release of

• ATP from a chloroplast carrying out photosynthesis

• Oxygen from a mitochondrion carrying out photosynthesis

• Glucose from a chloroplast carrying our respiration

• carbon dioxide from a mitochondrion carrying out respiration

The production of energy-rich ATP molecules is the direct result of

• recycling light energy to be used in the process of photosynthesis

• releasing the stored energy of organic compounds by the process of respiration

• breaking down starch by the process of digestion

• copying coded information during the process of protein synthesis

The flow of energy through an ecosystem involves many energy transfers. The diagram summarizes the transfer of energy that eventually powers muscle activity.

What is the process of cellular respiration represented by?

• arrow A, only

• arrow B, only

• arrow C, only

• arrows A, B, and C

Which phrase best describes cellular respiration, a process that occurs continuously in the cells of organisms?

• removal of oxygen from the cells of an organism

• conversion of light energy into the chemical bond energy of organic molecules

• transport of materials within cells and throughout the bodies of multicellular organisms

• changing of stored chemical energy in food molecules to a form usable by organisms

The energy found in ATP molecules synthesized in animal cells comes directly from

• sunlight

• organic molecules

• minerals

• inorganic molecules
