Respiration:
Misconceptions and Problems
When asked for evidence for respiration's inputs and outputs
students forgot to look for the appearance of CO2 or the
disappearance of glucose or O2. Evidence comes from
experimentation using the indicators given in the photosynthesis
unit!!!
Energy is NOT a molecule, it is NOT matter. When we use the word
energy we mean either light, or the energy found in chemical bonds
(and heat, which we tend to ignore). So technically you can’t say
respiration is used to make energy (its used to make ATP). However,
you can say Respiration is used to convert energy (from the chemical
bonds in Glucose to the Chemical bonds in ATP).
Similarly you can’t say photosynthesis is used to make energy (Its
used to trap light energy from the sun in the chemical bonds of
glucose).
THE PURPOSE OF RESPIRATION IS TO MAKE ATP
THE PURPOSE OF RESPIRATION IS TO MAKE ATP
THE PURPOSE OF RESPIRATION IS TO MAKE ATP
THE PURPOSE OF RESPIRATION IS TO MAKE
ATP
(The purpose of respiration is to convert the energy of chemical
bonds in glucose into energy of bonds in ATP).
CELLS do NOT conduct respiration to create CO2 for plants (CO2 is
a gaseous waste product for cells…it just so happens that plants
require it as an input)
