Homework

2. Chapter 3: The Organic Molecules of Life
Carbohydrates: sugars; energy and structure
Lipids: fats; energy storage and membranes
Proteins: Enzymes, hormones, metabolism and motion
Nucleic Acids: DNA/RNA, genetic information

3. Chapter 4: Inside the Cell
4.2 The Two Main Types of Cells
Prokaryotic Cells- lack a membrane- bound nucleus
Eukaryotic Cells- Has a nucleus that houses its DNA

5. Prokaryotic Cells: Bacteria and Archaea
Smaller in size and simple structure
Have a cell wall and a capsule (protective layer)
DNA is located in the nucleoid area
May have a flagella (tail-like appendage)

9. Chapter 5: The Dynamic Cell
5.1 What is Energy?
Energy-the capacity to do work

10. 5.2 ATP: Energy for Cells
ATP breaks down to release a phosphate group to form ADP and releases energy
Easily coupled (reactions paired where energy is released and energy is absorbed)

11. 5.3 Metabolic Pathways and Enzymes
ATP breaks down to release a phosphate group to form ADP and releases energy
Easily coupled (reactions paired where energy is released and energy is absorbed)

12. 5.4 Cell Transport Passive transport (no additional energy)
Simple diffusion: molecules move along a concentration gradient
Facilitated diffusion: molecules diffuse across a membrane with the assistance of a carrier protein

13. Osmosis: the diffusion of water
Isotonic solutions- cell neither gains nor loses water
Hypotonic solutions- cells gain water
Hypertonic solutions- cells lose water

15. Active transport (additional energy required)
Uses a transport protein
Includes exocytosis (secretion) and endocytosis (taken in)

16. Chapter 6 Energy for Life
6.1 Overview of Photosynthesis
Plants, algae, cyanobacteria convert sunlight to chemical energy
Chloroplasts take in carbon dioxide and water, chlorophyll absorbs solar energy
Photosynthesis creates carbohydrates
H2O+ CO2  CH2O + O2

17. 6.2 Light Reactions
Chlorophyll absorbs solar energy

18. 6.3 Calvin Cycle Reactions
C02 is taken in and a carbohydrate is formed.
Carbohydrate can be used to make a variety of molecules: glucose, cellulose, starch and parts of amino acids, glycerol, and fatty acids

19. Chapter 7: Energy for Cells
Chapter 7.1 Cellular Respiration
C6H12O6 + O2  CO2 +H2O
Occurs in several steps
Occurs outside and within the mitochondria in cells
Produces a great deal of energy- 36 ATP and heat
Other sources of energy can be used to fuel cellular respiration (such as fats and oils) but they do not produce as much ATP

20. 7.4 Fermentation Occurs when oxygen is not present Produces only 2 ATP
Provides a rapid burst of energy
Occurs in muscle cells, results in lactate (muscle fatigue)
Yeast and some bacteria produce CO2 and ethyl alcohol from fermentation
Used for wine, beer, and bread production

21. Equations Activity
Photosynthesis vs. Respiration

22. Review
The organelle that sorts proteins and sends them to their final destination is the: A) ribosome B) vacuole C) Golgi Apparatus D) lysosome

23. A protein molecule that functions as an organic catalyst to speed up chemical reactions in a cell is a
Enzyme
Substrate
ATP
DNA
A) Enzyme

24. The raw materials for photosynthesis are
Oxygen and water
Oxygen and carbon dioxide
Carbon dioxide and water
Carbohydrates and water
C) Carbon dioxide and water

25. Cellular respiration requires
Water and carbon dioxide
Glucose and oxygen
Oxygen and carbon dioxide
Water and glucose
B) Glucose and oxygen

26. Homework Read Part II: Genetics
Chapter 8, 9, 10, and 11 (do not do 12 and 13)
Please do any 10 questions from the “Testing Yourself” questions from the end of the chapters (8-11 only). Do at least two questions from each chapter.
