QuestionAnswer
pigment A colored chemical compound that absorbs light.
autotroph An organism that makes its own food.
stomata Small openings on the underside of a leaf through which oxygen and carbon dioxide can move.
respiration The process of which cells break down simple food molecules to release the energy they contain.
mitochondria Rod-shaped cell structures that convert energy in food molecules into energy the cell can use to carry out its functions.
heterotroph An organism that cannot make its own food.
fermentation The process of which cells break down molecules to release energy without using oxygen.
photosynthesis The process in which plants and some other organisms capture the energy in sunlight and use it to make food.
chloroplast A structure in the cells of plants and some other organisms that capture energy from sunlight and use it to produce food.
chlorophyll A green pigment found in the cells of plants, algae, and some bacteria.
Fermentation release more energy than respiration. false
What form do cells store energy in? carbohydrates
How do cells "withdraw" energy? By breaking down the carbohydrates in the process of respiration.
Respiration that takes place inside of cells is the same thing as breathing air in and out of the lungs. false
What events in respiration take place in only the first stage? Takes place in cytoplasm and glucose molecules are broken down.
What events in respiration take place in only the second stage? Takes place in the mitochondria and oxygen is involved.
What events in respiration take place in both stages? Energy is released.
What is respiration the opposite of? photosynthesis
What is photosynthesis the opposite of? respiration
What are the two types of fermentation? Alcoholic fermentation and lactic acid fermentation.
Where does alcoholic fermentation take place? In yeast and some other single celled organisms.
Where does lactic acid fermentation take place? In muscle cells.
CadiWaGO Carbon dioxide+Water=Glucose+Oxygen(photosynthesis)
GOCadiWaE Glucose+Oxygen=Carbon dioxide+Water+Energy (respiration)
What is the order in where respiration takes place? Cytoplasm first, mitochondria second.
When does fermentation take place? When there is little to no oxygen available.
Where is lactic acid fermentation also found? In sour milk products.
What are photosynthesis, respiration and fermentation? cellular processes
What does an arrow mean? yields
energy The ability to do work or cause change.
ATP A type of transport protein.
aerobic Use of oxygen adequately to meet the energy demands during longer periods of exercise.
anaerobic Use of oxygen adequately to meet the energy demands during short periods of exercise.
chemiosmosis The diffusion of hydrogen ions.
reactants The raw materials that are used to create the end products.
products What is produced from a cellular process.
