404737636Where inside the cell does respiration take place?Mitochondrion
404737637The pathway for cellular respiration requires oxygen, meaning that it is........Aerobic
404737638Fermentation occurs in the absence of oxygen, meaning that the environment is...Anaerobic
404737639What are the two types of fermentation?Lactic acid and Alcoholic
404737640What are the products of alcoholic fermentation?Alcohol + Energy + Co2
404737641Name one organisms that uses alcoholic fermentation?Yeast
404737642What are the products of lactic acid fermentation?Lactic Acid + Energy + Co2
404737643Name one organism or part of the body that uses lactic acid fermentation?Muscles

404746609ATP and ADPATP provides a chemical fuel that cells need and is potential for energy release. ATP is basic energy source for all cells. The role of ATP : 1. Active transport 2. Building proteins 3. Cell response and communication
404746610Chemical storageADP is short term energy storage and Glucose is long term storage.
404746611Light Absorption spectrumThe different wavelengths of the visible spectrum as different colors. There are seven colors. (Red, orange, yellow, green, blue, indigo, and violet)
404746612Photosynthesis(6)CO2 + (6)H2O -----> C6H12O6 + (6)O2 Photosynthesis uses the sunlight energy to convert water and CO2 into high energy sugars and O2
404746613ChloroplastsChloroplasts contain thylakoids (saclike photosynthetic membranes), and stroma (outside of thylakoids)
404746614ChlorophyllChlorophyll is the major pigment in plants. Chlorophyll a - Bluish Green Chlorophyll b - Yellowish green
404746615PigmentsPigments are light absorbing molecules. Plants reflect the color that was not absorbed, and people too. ex:Carotene-Reflect orange Xanthophyll- Reflect yellow (?) Anthocyanin - Reflect red
404746616Light dependent reactionsLight dependent reaction takes place within Thylakoid membranes. This reactions requires sunlight and produces oxygen gas and stores energy.
404746617Light independent reactionsLight independent reactions (Dark cycle, Calvin cycle) takes place in stroma. This reaction doesn't require sunlight, uses ATP and CO2 from the air to produce high - energy sugar (starch). Finally, the plant grows!
404746618Factors1. Temperature 2. Light intensity 3. Water
404746619Cellular respirationC6H12O6 + O2 -----> CO2 + H2O + Energy (ATP)
404746620GlycolysisDuring glycolysis, 1 molecules of glucose (6 - carbon compound) is transformed into 2 molecules of pyruvic acid (3 - carbon compound). Glycolysis produces 2 ATP molecules.
404746621Krebs CyclePyruvic acid breaks down into carbon dioxide and 34 molecules of ATP. Krebs cycle takes place in Mitochondria.
404746622Electron TransportThe last part of respiration. The electron transport chain uses the high energy electrons from glycolysis and the Krebs cycle to convert ADP into ATP. Electron Transport takes place in Mitochondria.
