Discover the molecules used in respiration Texas Gateway

Look at the video. Things to think about: are any molecules in aerobic respiration the same in cellular respiration? Does this surprise you?  Why/why not?

HS-LS1-7.    Use a model to illustrate that cellular respiration is a 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.

[Clarification Statement: Emphasis is on the conceptual understanding of the inputs and outputs of the process of cellular respiration.] [Assessment
Boundary: Assessment should not include identification of the steps or specific processes involved in cellular respiration.]
