Biology-chapter 7 Biology-chapter 7 Photosynthesis/Cellular Respiration

Question Answer
organisms that make their own food autotrophs (also called producers) ex. plants
organisms that depend on other organisms for their energy heterotrophs (also called consumers) ex. humans
Unit of energy in cells (primary source of usable energy in cells) ATP (adenosine triphosphate)
process where simple sugars are formed from carbon dioxide and water in the presence of light and chlorophyll photosynthesis-solar energy is converted to chemical energy
carbon dioxide, water, light, chlorophyll inputs of photosynthesis
glucose, oxygen outputs of photosynthesis
a light absorbing molecule that functions in photosynthesis pigment
the primary catalyst (green pigment) used in photosynthesis chlorophyll (specifically chlorophyll a)
When ATP releases energy (a a small, gentle release), it then becomes this molecule which can be recycled back into ATP ADP (adenosine diphosphate)
type of energy used in photosynthesis light energy (usually SOLAR)
breakdown of foods (specifically glucose) to release energy including aerobic and anaerobic types cellular respiration-chemical energy is changed into usable energy
processes that build molecules and store energy anabolism
processes that break down molecules and release energy catabolism
processes that use oxygen aerobic
processes that do not need or require oxygen anaerobic
the sum of all reactions that occur in a living organism metabolism
1st phase of photosynthesis that requires light and occurs in the thylakoids of the chloroplast and results in ATPs and NADPH light dependent phase
2nd phase of photosynthesis that is also called the light independent phase and results in production of glucose calvin cycle
In photosynthesis, the process where a water molecule is split into hydrogen ions, electrons, and oxygen photolysis
1st phase of cellular respiration: occurs in the cytoplasm, is anaerobic, and results in 2 pyruvic acid molecules and 2 ATPs glycolysis
2nd phase of cellular respiration: occurs in the mitochondria, is aerobic, and results in 2 ATPs citric acid cycle (also known as Krebs cycle)
last phase of cellular respiration: occurs in the mitochondria, is aerobic, and results in 32 ATPs ETC (electron transport chain)
process that occurs if there is no oxygen after pyruvic acid is made in glycolysis, results in lactic acid or ethyl alcohol fermentation-2 ATPs made because glycolysis still occurs-two types of fermentation:alcoholic and lactic acid
thylakoid a flattened, membrane-bound sac inside a chloroplast where the light-dependent phase of photosynthesis takes place
stroma material within a chloroplast that surrounds the thylakoids
glucose Molecule that all living things use to get their energy from (used in the process of cellular respiration)
