Cellular respiration is one of the most important cellular processes. This power point covers cellular respiration in detail emphasizing the following points. Cellular respiration starts in the cytoplasm with glycolysis. When oxygen is present the pyruvic acid moves into the mitochondria for the Krebs cycle to take place.
When oxygen is not available fermentation takes place. Cellular respiration produces 36 ATP molecules. Cellular respiration is the link between the producers and consumers.
Students will understand the importance of cellular respiration for all living organisms, the three main processes of cellular respiration, and the components that allow cellular respiration to take place. Students will also understand what happens when oxygen is missing.
GREAT FOR ANY STATE!
Texas Biology TEKS
(4) Science concepts. The student knows that cells are the basic structures of all living things with specialized parts that perform specific functions and that viruses are different from cells. The student is expected to:
(B) investigate and explain cellular processes, including homeostasis, energy conversions, transport of molecules, and synthesis of new molecules; and
(9) Science concepts. The student knows the significance of various molecules involved in metabolic processes and energy conversions that occur in living organisms. The student is expected to:
(B) compare the reactants and products of photosynthesis and cellular respiration in terms of energy and matter;
NEXT GENERATION SCIENCE STANDARD
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.]
HS-LS2-3. Construct and revise an explanation based on evidence for the cycling of matter and flow of energy in aerobic and anaerobic conditions. [Clarification Statement: Emphasis is on conceptual understanding of the role of aerobic and anaerobic respiration in different environments.]
