Essential Standard:
Bio 1.2 Analyze the Cell as a Living System
Bio 4.2 Analyze the relationships between biochemical processes and energy use in the cell
Clarifying Objectives:
Bio.4.2.1 Analyze photosynthesis and cellular respiration in terms of how energy is stored, released, and transferred within and between these systems.
Bio 4.2.2 Explain ways that organisms use released energy for maintaining homeostasis (active transport).
Unpacking – What does this standard mean a child will know, understand, and be able to do?
Bio.4.2.1
• Analyze overall reactions including reactants and products for photosynthesis and cellular respiration and factors which affect their rates (amounts of reactants, temperature, pH, light, etc.).
• Compare these processes with regard to efficiency of ATP formation, the types of organisms using these processes, and the organelles involved. (Anaerobic respiration should include lactic acid and alcoholic fermentation.)
Note: (1) Instruction should include the comparison of anaerobic and aerobic organisms. (2) Glycolysis, Kreb’s Cycle, and Electron Transport Chain are not addressed.
Bio 4.2.2
Conclude that energy production by organisms is vital for maintaining homeostasis and that maintenance of homeostasis is necessary for life. Examples: Active transport of needed molecules or to rid the cell of toxins; movement to avoid danger or to find food, water, and or mates; synthesizing needed molecules.
Key Vocabulary:
3rd Tier Words: photosynthesis, cellular respiration, reactant, product, ADP/ATP, phosphate group, energy, aerobic, anaerobic, fermentation (lactic acid / alcoholic), chloroplast, mitochondria, bond, exothermic, endothermic, digestion, light independent, light dependent reactions
2nd Tier Words: pigment, recycled, affect, effect, expand, control, collect, inflate, produce, interact, span, interior, exterior, barrier, submerge, distributed, maintain, net movement, shrivel, turgid, flaccid, wilt, steep, composed
Common Misconceptions:
4.2.1
How does energy from the sun become energy for life?
Are food and energy the same thing?
4.2.2
Why do organisms need energy?

Common Misconceptions:
- Plants get organic food substances such as starch and sugar or protein from the soil.
- Water is food for plants.
- Light dependent reactions occur in the presence of light while light independent reaction occurs in the dark.
4.2.1
How does energy from the sun become energy for life?
Are food and energy the same thing?
- I will summarize the goal of photosynthesis (to produce food) and the goal of cellular respiration (to use food to produce energy for cells).
- I will explain the equation for photosynthesis, identifying reactants and products.
- I will discuss the need for organisms to break down the food that they have produced (autotrophs) or have taken in (heterotrophs) in order to produce an energy molecule that cells can use for energy.
- I will explain the equation for cellular respiration, identifying the reactants and products.
- I will identify the organelles in cells where photosynthesis and cellular respiration occur.
- I will differentiate between aerobic and anaerobic respiration (fermentation) and will explain that more energy (ATP) is produced in aerobic respiration.
- I will discuss the types of living organisms that are likely to carry out aerobic vs. anaerobic respiration.
- I will discuss the types of organisms that produce lactic acid vs. alcohol when using anaerobic respiration.
- I will analyze graphs/information about factors that affect the rate of photosynthesis or cellular respiration, including amounts of reactants, temperature, light, and pH.
- I will explain that the energy in ATP is stored in a chemical bond, and that ATP can be recycled.
4.2.2
Why do organisms need energy?
- I will evaluate an organism’s need for energy and relate to the STERNGRR life processes (synthesis of molecules, transport of materials, growth, reproduction)
- I will explain that in order for an organism to maintain homeostasis, energy is required for the STERNGRR life processes (synthesis, excretion, regulation).
- I will provide examples of maintaining homeostasis and relate to STERNGRR and the need for energy.
