3/20 - Energy Transformations: For each statement below, check if the statement matches cellular
respiration, photosynthesis, or both. Use this video if you need help http://tinyurl.com/energycycles
Photosynthesis
Cellular
Respiration
ATP is produced
Occurs in all living organisms, both plants and animals
Products are 6CO2, 12H2O, and energy
Can only occur in the presence of sunlight
Equation is 6CO2 + 12H2O + light  C6H12O6 + 6O2 + 6H2O
Requires energy to occur
Glucose is broken down into water, carbon dioxide, and energy
Stages of process include glycolysis, Krebs cycle, and electron transport chain
Energy for reaction is obtained from breaking chemical bonds
Electron transport chain is used to pump protons across membranes
Occurs in the mitochondria of cells
Main function is the breakdown of food (energy release)
Carbon dioxide is absorbed and oxygen is released
Products are 6CO2, 6H2O, and energy
Occurs only in plants, algae, and some bacteria
Main function is the production of food (energy capture)
Occurs in the chloroplasts of cells
Catalyst for the reaction is chlorophyll
Energy for reaction is obtained from photons in sunlight
No catalyst is required for this reaction
Stages include the light dependent and the light independent reactions
Equation is 6O2 + C6H12O6  6CO2 +6H2O + ATP (energy)
3/21 - DNA: DNA is the ‘instruction manual’ for all of life’s processes. In order for the body to ‘read’ these
instructions, each cell must undergo a process of DNA replication and protein synthesis (transcription and
translation). Using the documents provided, describe the process in which the instructions in DNA create
proteins.
Your paragraph should include the following:
 Introduction (1 sent.)
 DNA replication (1-2 sent.)
 Transcription (1-2 sent.)
 Translation (1-2 sent.)
 Conclusion (1 sent.)

3/24 - Ecological Changes: In order for an ecosystem to develop, it must undergo certain stages called
succession. Primary and secondary succession must occur in order to produce a climax community. Using the
document provided, describe the process in which an ecosystem changes over time to create a climax
community.
Your paragraph should include the following:
 Introduction (1 sent)
 Describe what type of succession is shown (1-2 sent)
 Explain what could cause this type of succession (1-2 sent)
 Explain climax communities (1-2 sent)
 Conclusion (1 sent)

3/25 – Ecosystems: An ecosystem is composed of a wide variety of essential components, both living and
nonliving. Using the document provided, describe the different factors in a desert biome and how they are all
interconnected.
Your paragraph should include the following:
 Introduction (1 sent)
 Describe abiotic factors of desert (1-2 sent)
 Describe biotic factors of desert (1-2 sent)
 Describe how biotic & abiotic factors are
interconnected (1-2 sent)
 Conclusion (1 sent)

3/26 - Heredity: Your genes are the biggest factor in determining who you are. Even children of the same
parents can have very different physical characteristics. Organisms that look the same can actually have very
different genes, depending on whether the specific alleles are dominant or recessive. In a paragraph, explain
how an organism’s genotype relates its phenotype and how a Punnett square can be used to predict the
offspring of a mating pair.
Your paragraph should include the following:
 Introduction (1 sent)
 Dominant and recessive alleles (1-2 sent)
 Genotype vs. phenotype (1-2 sent)
 Punnett square (1-2 sent)
