Bioenergetics Flashcards
What does photosynthesis transfer?
photosynthesis transfers light energy into chemical energy inside plants.
Is photosynthesis exothermic or endothermic?
Photosynthesis is an endothermic reaction.
what are the reactants for photosynthesis?
The reactants in photosynthesis are carbon dioxide and water.
The products of photosynthesis are..?
glucose and oxygen.
Substances associated with photosynthesis have the following chemical symbols:
Carbon dioxide
Water
Oxygen
Glucose
Carbon dioxide - CO2
Water - H2O
Oxygen - O2
Glucose - C6H12O6.
Glucose made in photosynthesis is used for:
production of cellulose cell walls, producing amino acids, producing fats and oils and can be stored as insoluble starch.
The rate of photosynthesis can be affected by:
carbon dioxide concentration
light intensity
temperature
amount of chlorophyll.
is aerobic respiration is an endothermic or exothermic reaction?
Aerobic respiration is an exothermic reaction
where does Aerobic respiration take place?
Aerobic respiration takes place mitochondria.
reactants in aerobic respiration are…?
glucose and oxygen.
products of aerobic respiration are…?
carbon dioxide, water and energy.
energy released in aerobic respiration is used for:
movement, keeping warm and chemical reactions to build large molecules.
During exercise what rates and volume increase
During exercise, heart rate, breathing rate and breath volume increases.
Anaerobic respiration does not require
Anaerobic respiration does not require oxygen.
Anaerobic respiration produces …. nrg then aerobic respiration
less energy.
…. acid is produced during anaerobic respiration and is toxic to the body.
Lactic acid is produced during anaerobic respiration and is toxic to the body.
Oxygen debt is the
amount of oxygen needed to break down the lactic acid produce in anaerobic respiration.
Anaerobic respiration in plant and yeast cells produces
carbon dioxide and ethanol.
Anaerobic respiration in yeast can be used in the
manufacture of bread and alcohol.
Metabolism is the sum of
all reactions inside the cells of the body.
Metabolism includes:
production of lipid molecules,
production of amino acids,
respiration,
breakdown of excess protein
conversion of glucose to starch and glycogen.
