Pyruvate
Before cellular respiration, glucose is broken down in glycolysis into 2 3-carbon molecules called
Sunlight
Chemosynthesis is a process through which some organisms use energy from chemicals in their environment to build sugars in the absence of
has a phosphate group removed
Energy is released from an ATP molecule for cellular processes when it
capture the transfer energy
The function of the light-dependent reactions is to
Carbon dioxide
The light-independent reactions of photosynthesis need
Chlorophyll
The main light-absorbing molecules found in plant leaves are called
Glycolysis
The part of cellular respiration in which glucose is broken down is called
Mitochondria
The part of cellular respiration that needs oxygen takes place inside the
ATP and carbon dioxide
Two products of the krebs cycle are
Producer
What is the term for an organism that makes its own source of chemical energy?
ATP
What molecule carries chemical energy that cells use for their functions?
Krebs Cycle
What provides the electron transport chain in cellular respiration with the energy it needs
the breakdown of carbon-based molecules into smaller molecules
Where does the chemical energy to produce ATP come from?
Alcohol
Which end product of alcoholic fermentation is important in baking?
Lactic acid
Which end product of fermentation causes the burning feeling in muscles that are working hard?
carbon dioxide
Which of the following is a reactant in photosynthesis?
Chemical compounds
Which of the following is the source of energy used in chemosynthesis?
Carbohydrates
Which of the following molecules found in the foods we eat is most commonly broken down to make ATP?
Carbon-based molecules from food and oxygen are used to make ATP
Which of the following statements best describes cellular respiration?
chloroplasts absorb sunlight and store chemical energy
Which of the following statements best describes the process of photosynthesis?
they use chemical energy
Which of the following statements is true for all cells?

Which of the following types of organism uses cellular respiration for their cellular energy
Takes place without oxygen
Which phrase about fermentation is correct
carries energy
Which phrase best describes the function of the ATP molecule?
allows glycolysis to continue making small amount of ATP
Which phrase best describes the main role of fermentation?
Cellular respiration
Which process breaks down sugars to make ATP when oxygen is present?
