  1. Homework

Check Class Schedule or Mr. Martin’s class webpage (rcboe.org/arj) for due dates and details

  1. Read Chapter 8 in your textbook
  2. Review and answer the Key Concepts / Assessment Statements for each section. Answer in your notebook binder.

KEY CONCEPTS / ASSESSMENT STATEMENT

  1. 8.1 – Energy and Life
  1. Explain how ATP and ADP are related (ATP / ADP cycle)
  2. Draw & label a diagram of ATP.
  3. What happens when a phosphate BREAKS away from ATP?
  4. List types of molecules are broken down (metabolized) to make ATP.
  5. Explain the difference between autotrophs and heterotrophs
  1. 8.2 – Photosynthesis: An Overview
  1. Write the chemical equation for photosynthesis.
  2. What are the reactants and the products of photosynthesis
  3. State that photosynthesis involves the conversions of light energy into chemical energy (sugars)
  4. State that chlorophyll is the main photosynthetic pigment.
  5. State that light energy is used to produce ATP, & split water molecules to from oxygen & hydrogen (Light Dependent Reaction)
  6. State that ATP & hydrogen (derived from Light Reactions) is used to fix carbon dioxide and to make organic molecules such as glucose.
  7. Explain that the rate of photosynthesis can be measured directly by to production of oxygen or the uptake (consumption) of carbon dioxide or indirectly by the increase in biomass.
  8. Outline effects of temperature, light intensity and carbon dioxide concentration on the rate of photosynthesis (these are graphs).

Figures/Graphs to know:

Reaction / Stage of Photosynthesis / Reactants
(goes in) / Products
(comes out) / Location
Light Dependent Reaction / H2O
water / O2
oxygen / Within the thylakoid
Light Independent Reaction (Calvin Cycle) / CO2
carbon dioxide / C6H12O6
glucose/sugars / In stroma / outside the thylakoid

  1. Increasing light intensity on rate of photosynthesis

  1. Increasing CO2 concentration of rate of photosynthesis
  1. Increasing temperature on rate of photosynthesis

  1. Absorption spectrum of chlorophyll & action spectrum
