LS1-7 The Chemistry of Respiration

Biology and Life Science Safety Guidelines

Phenomenon

Discover the molecules used in respiration Texas Gateway

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.]
