captures its own energy and uses carbon dioxide to synthesize organic molecules. makes its own food.
captures energy from sunlight and uses carbon dioxide to make carbohydrates(energy). photosynthesizes.
uses energy from inorganic substances such as sulfides or nitrates and uses carbon dioxide to make carbohydrates(energy). does not photosynthesize.
uses ready made organic molecules obtained from other organisms. take in food from outside source.
captures energy from light but still needs an additional energy source(organic molecules) present such as methanol to meet all energy requirements
metabolic pathway used by most autotrophic and heterotrophic organisms to break down glucose which is needed for energy. doesn't require oxygen but can occur when oxygen is present.
metabolic process that keeps glycolysis going by further breaking down glucose when oxygen is not present. occurs after glycolysis and oxygen is not present.
homolactic acid fermentation
pyruvic acid is converted to lactic acid, creating foods such as yogurt and cheese
pyruvic acid is converted to ethyl alcohol. yeast does this to make bread, wine, beer, etc.
aerobic metabolism. occurs when oxygen is present and further breaks down pyruvic acid created during glycolysis.
the amount of energy released in respiration as compared to that of initial metabolism of glucose
anaerobic metabolism --->______ or _____
homolactic acid fermentation and lactic acid or alcoholic fermentation and ethyl alcohol
an increase in the number of cells that occur by cell division, not by size increase
a cell duplicates all its components and then divides in half to form two cells. this is asexual reproduction.
when a small new cell develops from the surface of an existing cell and separates from the parent cell.
organisms adapt to their medium and grow at an exponential or logarithmic rate. cell division occurs rapidly.
the rate of cells dividing slows to the rate of cells dying and the number of cells remains constant.
the medium and environment becomes less supportive for cell growth and division. the number of live cells decrease at a logarithmic rate.
when cells dont completely separate in cell division
they form tetrads, chains, sarcinaes, or grape like clusters.
