Photosynthesis and Respiration Study Guide
- Why? To convert sunlight energy to chemical energy
1. All green plants (Plant Kingdom),
2. photosynthetic bacteria,
3. plant-like protists (algae)
- Where? Leaves(organs), specifically chloroplasts
- When? During daylight/sunlight (even on a cloudy day)
- What? Chloroplasts [are making food/glucose]; “Mean green photosynthesizing machines”
Define Photosynthesis. “The Putting Together With Light”
- Producers/autotrophs - organisms that can make their own food.
- We get so much from the process of photosynthesis: food, clothing medicines, wood, oxygen, paper, pencils, flowers, and so much more!
- Why To produce ATP
- Whom? All aerobes (organisms that use oxygen); producers and consumers
3. Some bacteria
5. Some fungi
- Where? Mitochondria
- When? Constantly
- What? Food/glucose is being broken down to release energy
Define respiration. The metabolic processes whereby certain organisms obtain energy from organic molecules; processes that take place in the cells and tissues during which ATP energy is released and carbon dioxide and water is produced.
- Why? To produce ATP
- Whom? All anaerobes (organisms that do not use oxygen)
2. Some bacteria
- Where? Cytoplasm
- When? Constantly
- What? Food/glucose [is being fermented]
Define fermentation. Fermentation is a process by which food is broken down
without oxygen, in living organisms, to produce ATP.
- What industries use fermentation?
1. Baking (CO2)
2. Brewing (Alcohol and CO2)
3. Dairy (Lactic Acid)
- What are the reactants ? One sugar (C6H12O6) (and a ATP investment).
- What are the products of fermentation? ATP and [CO2, alcohol] OR [ lactic acid]
Consumers/heterotrophs - organisms that must obtain food sources from other organisms.
- Herbivores - eat only plants
- Carnivores - eat only meat
- Omnivores - eat both plants and meat
- Scavengers - organisms that eat dead organisms
- Decomposers/Detritivores - Break down organisms, “nature’s recyclers”
- Arrows point towards the organism obtaining energy or eating!
Metabolism - The chemical processes that occur within a living organism in order to maintain life.
Enzymes - Help speed up chemical processes by breaking substances apart or putting substances together.
