EOC Review #3: Photosynthesis, Cell Respiration, DNA, Mitosis, and Protein synthesis Christopherson
Photosynthesis Photosynthesis I
Photosynthesis Function To produce glucose (food) for producers The formula for glucose: C6H12O6
Photosynthesis: How? Plants absorb sunlight energy, carbon dioxide and water to make glucose
Photosynthesis: Location Chloroplast Chlorophyll: Pigment Producer Leaf Leaf Cross-section
Pigments Found inside the thylakoid Absorb sunlight energy and give plants their color.
Photosynthesis Summative Equation (Formula) Sunlight Energy CO2 H2O C6H12O6 O2 + + Reactants What is needed Products What is produced
Cell Respiration I: ATP and Anaerobic Respiration Christopherson
Purpose of Cell Respiration The process in which glucose (food) is broken down into ATP (usable energy) ATP C6H12O6 C6H12O6
ATP Structure Contains adenosine, sugar, and three phosphates
Photosynthesis Summative Equation (Formula) C6H12O6 O2 CO2 + H2O ATP + + Reactants Need? Products Produced?
Anaerobic Respiration Respiration that occurs without oxygen present
Organisms that undergo Anaerobic Respiration: All living things
Process: Anaerobic Respiration Simple Organisms Glucose: C-C-C-C-C-C ATP Pyruvate: C-C-C and C-C-C Fermentation
Breaking down of Pyruvate: Simple Organisms - Result Pyruvate is broken down into waste. It’s trash. This process is Fermentation. Pyruvate
Breaking down of Pyruvate Simple Organisms Bacteria Yeast
Process: Anaerobic Respiration Complex Organisms Glucose: C-C-C-C-C-C ATP Pyruvate: C-C-C and C-C-C To the Mitochondria (Aerobic Respiration)
Aerobic Respiration Respiration that occurs with oxygen present
Organisms that undergo Aerobic Respiration: Complex Organisms(Everything BUT Bacteria and Yeast)
Mitochondria Function: Breaks down sugar into ATP (usable form of energy); Powerhouse of the cell Location: Throughout the cell
Aerobic Respiration RESULT Pyruvate C-C-C and C-C-C O2 O2 is the key to the mitochondria ATP ATP ATP ATP ATP ATP ATP ATP ATP ATP ATP ATP ATP ATP ATP ATP ATP ATP ATP ATP
DNA Structure and Discovery Christopherson
DNA: Deoxyribonucleic AcidDNA is a Nucleic AcidMonomer: Nucleotide
Structure of a Nucleotide a. Adenine 1. Phosphate b. Thymine c. Cytosine d. Guanine 3. Nitrogen Base 2. Deoxyribose
Structure of DNA Phosphate Deoxyribose Nitrogen Bases

What is a Body Cell? All the cells that make up the “body” of an organism.
What is a Homologous Pair? A pair of chromosomes that are very similar; one is from your mom and the other from your dad
Diploid? Formula: 2n n = the number of chromosomes 2 = that homologous pairs are present -Normal number of chromosomes in organisms body cell
Purpose of the Cell Cycle To grow, replace old cells, or reproduction
Location of the Cell Cycle Within an organisms body cells
1st Step of the Cell Cycle Interphase: Cell prepares to divide by making more organelles and cytoplasm (G1 and G2); Replicates DNA (S)
2nd Step of the Cell Cycle Mitosis: The replicated DNA is separated Made up of PMAT Prophase, Metaphase, Anaphase, Telophase
3rd Step of the Cell Cycle Cytokinesis: The cell divides the organelles and cytoplasm into the new cell
End Result of the Cell Cycle Two identical cells with the same number of chromosomes Interphase Mitosis Cytokinesis
If an organism has 50 chromosomes and it undergoes mitosis, how many chromosomes will be present in the new cells?
If an organisms diploid number chromosome is 100, how many chromosomes will be present in the new cells?
What is a GENE? Instruction manual for our body Portion of the DNA that “codes” (has the directions) for a specific trait.
Where is a Gene? • Within DNA • The nitrogen bases spell out the instructions
RNA Ribonucleic Acid Make up of Nucleotides Contains Phosphorus
RNA Nucleotide A Phosphate Nitrogen Base C B Guanine Cytosine Ribose Adenine Uracil
DNA versus RNA: # of Strands 2 strands 1 strand
