Unit 2. Chapters 9-16. Cell Processes 1. Cellular Respiration‚ Photosynthesis‚ Cell Cycle‚ Mitosis‚ Meiosis‚ & Genetics. Note A: All work must be hand-written‚ including charts & diagrams. Note B: each answer requires more than one sentence & use diagrams whenever possible; failure to use diagrams will result in less points. Chapter 9 Outline 1) Principles of Energy Conservation a) Cellular respiration and fermentation are catabolic(energy – yielding) pathways b) Cells must recycle the ATP

how starch and cellulose are treated to allow them to be used by the yeast? One potential ethanol feedstock is starch. Starch molecules are made up of long chains of glucose molecules. Thus‚ starchy materials can also be fermented after breaking starch molecules into simple glucose molecules. Examples of starchy materials commonly used around the world for ethanol production include cereal grains‚ potato‚ sweet potato‚ and cassava. A great amount of ethanol fuel is currently produced by starch

Keeping conditions inside the body the same is called homeostasis. It’s not easy. Lots of things have to happen‚ e.g. energy transferred between body and environment‚ carbon dioxide is a waste product of respiration and has to be transported by the bloodstream to the lungs where it is breathed out‚ waste and waste products are filtered out of the blood and excreted in the urine. An incubator has a temperature sensor‚ a thermostat with a switch and a heater. Negative feedback happens when one factor

of tube tail. o Why is alcohol fermentation needed in yeast to carry out glycolysis In an environment absent of oxygen‚ yeast undergoes alcohol fermentation in order to continue ATP production but also to recycle NAD+ that is needed for glycolysis. Without this recycling‚ glycolysis and therefore cellular respiration cannot proceed and organism will die. o How efficient is fermentation- 2% (2 ATP) efficient compared to aerobic respiration‚ which is 39% (36 ATP) efficient at capturing the energy

energy for their cellular processes. In biological processes‚ the immediate energy source is often in the form adenosine triphosphate (ATP). The nucleotide ATP maintains both catabolic and anabolic reactions. An example of a catabolic reaction is respiration where large molecules are broken down into smaller ones with energy released. An example of an anabolic reaction is photosynthesis where small molecules are built up into larger ones using energy. ATP is built up from ADP and inorganic phosphate

Cells are joined together to form threads‚ called hyphae. Hyphae contain many nuclei‚ because they are made from many cells. 4. Cell walls are made from chitin (a protein) 5. They store carbohydrates as glycogen. Examples include Mucor and Yeast (which is single celled). Bacteria: 1. Made from single cells 2. Cells do not contain a nucleus‚ but have a small piece of circular DNA instead (a bacterial chromosome). 3. Some bacteria can carry out
