SECOND SEMESTER
(04/19-04/23)
Topic: Anaerobic Respiration
Standard: HS-LS1-2, HS-LS2-2, HS-LS2-7 (Unifying Themes of Biology)
Objectives (Students will be able to understand that):
- Anaerobic respiration takes place when there is too little oxygen for aerobic respiration to take place.
- Anaerobic respiration involves the conversion of fuel molecules, such as glucose, into energy.
- During fermentation, glycolysis is the only energy extraction pathway that takes place.
- Lactic acid fermentation takes place when the heart and lungs are unable to supply enough oxygen to meet the body’s energy demand.
- In lactic acid fermentation, 2 lactates are produced.
- In yeast, alcohol fermentation takes place when oxygen levels are low.
- In alcohol fermentation, 2 ethanol molecules are produced.
- In total, only 2 ATP are produced from anaerobic pathways like fermentation.

(04/12-04/15)
Topic: Cellular Respiration
Standard: HS-LS1-2, HS-LS2-2, HS-LS2-7 (Unifying Themes of Biology)
Objectives (Students will be able to understand that):
- Aerobic cellular respiration is a biochemical pathway made up of 4 series of reactions: glycolysis, pyruvate oxidation, citric acid cycle, and oxidative phosphorylation.
- Glycolysis is a reaction that converts glucose into 2 pyruvates.
- Pyruvate oxidation is a reaction that converts each pyruvate into Acetyl CoA.
- The citric acid cycle is a reaction that completes the breakdown of glucose and fuels the production of ATP.
- Oxidative phosphorylation is a reaction that uses energy carrying molecules produced in the citric acid cycle to mass produce ATP.
- In total, 36 ATP are produced by aerobic cellular respiration.

Homework 2: Lesson 7.1 Micro Lab
(04/05-04/08)
Topic: Cellular Respiration
Standard: HS-LS1-2, HS-LS2-2, HS-LS2-7 (Unifying Themes of Biology)
Objectives (Students will be able to understand that):
- Energy is the capacity to move or change matter.
- Cellular respiration is the controlled release of energy from organic molecules, such as glucose.
- ATP is the primary energy carrying molecule used by cells to fuel their cellular processes.
- ATP is composed of an adenine base, ribose sugar, and 3 phosphate (PO4) groups.
- The 3 phosphate groups within ATP are commonly referred to as Pi.
- Phosphorylation refers to the chemical reactions that make ATP by adding Pi to ADP.
- ADP is an energy carrying molecule that contains 2 phosphate groups.
- Enzymes help break and reform PO4 bonds in a process called substrate-level phosphorylation.
- Cellular respiration takes place within mitochondria.
- NAD+ is an electron carrier that becomes NADH as it takes on 1 hydrogen and 2 electrons.
- FAD is an electron carrier that becomes FADH2 as it takes on 2 hydrogens and 2 electrons.

Homework 2: Lesson 7.1 Micro Lab
(03/22-03/25)
Topic: Passive Transport
Standard: HS-LS1-2, HS-LS2-2, HS-LS2-7 (Unifying Themes of Biology)
Objectives (Students will be able to understand that):
- Once autotrophs acquire energy from the sun, it is stored in organic compounds, such as glucose, during a process called photosynthesis.
- A biochemical pathway is a series of reactions where the product of one reaction is the reactant of the next.
- Chloroplasts are double membrane organelles with an inner membrane folded into disc-shaped sacs called thylakoids.
- Sunlight, or white light, is made of different wavelengths or colors carrying different amounts of energy.
- A pigment is a substance that only absorbs certain wavelengths.
- Chlorophyll, the most common pigment in plants and algae, only absorbs red, blue, or violet light.
