Photosynthesis & Cellular Respiration - Big Idea:
A. What is the equation, what are the reactants, what are the products
and where do they come from?
A. A chemical equation describes a chemical
reaction. Reactants are starting materials and are written
on the left-hand side of the equation. Products are the
end-result of the reaction and are written on the righthand side of the equation.
B. What process is common to both cellular respiration and
photosynthesis?
A. In both photosynthesis and respiration, chemical energy
is produced in the form of ATP. In photosynthesis, the
plant uses carbon dioxide, solar energy, and water to give
glucose and oxygen. In respiration, the energy is broken
down, and glucose and oxygen are converted to carbon
dioxide and water.
C. What comprises the mass of plants as they grow?
A. The mass of a tree is primarily carbon. The carbon comes
from carbon dioxide used during photosynthesis
D. What is the difference between the light dependent and light
independent reactions in photosynthesis and how are they
interlinked?
A. The light-dependent reactions convert light energy into
chemical energy, producing ATP and NADPH. The lightindependent reactions use the ATP and NADPH from
the light-dependent reactions to reduce carbon dioxide
and convert the energy to the chemical bond energy in
carbohydrates such as glucose.
E. What is the final electron receptor in cellular respiration?
A. To carry out aerobic respiration, a cell requires oxygen as
the final electron acceptor.
Multiple Choice Review- Energy Processing
