chlorophylls the pigments that cause plants to appear green
accessory pigments that transfer their energy to chlorophyll a
carotenoids these pigments absorb violet and blue waves but reflect reds, yellows and oranges
photons packets of energy from the sun that have a wavelike motion through space
chlorophyll a this is the main pigment of photosynthesis
chloroplast the structure where the two stages of photosynthesis occur
pigments molecules that can absorb or reflect light
The light dependent reactions are necessary to make ATP
Plant cells produce O2 during photosynthesis by splitting water
Chlorophyll and the other plant pigments are found in the thylakoid membrane system
Plants need ____ and _____ to carry on photosynthesis carbon dioxide, water
photosynthesis or respiration? Krebs cycle respiration
photosynthesis or respiration? Calvin cycle photosynthesis
photosynthesis or respiration? anabolic reaction photosynthesis
photosynthesis or respiration? catabolic reaction respiration

photosynthesis or respiration? water is a final product respiration
photosynthesis or respiration? carbon dioxide is a final product respiration
photosynthesis or respiration? acetyl CoA is a reactant respiration
Krebs cycle a stage of aerobic respiration where carbon atoms are rearranged and recycled
oxygen the final electron acceptor in the aerobic pathway (respiration)
mitochondrion site of the aerobid pathway (respiration)
electron transport final sate of aerobic respiration, produces a high amount of ATP
enzymes catalyze each reaction step in the energy-releasing pathways (respiration)
ATP the energy form that drives all metabolic reactions in cells
glycolysis all organisms do at least this first stage of respiration
aerobic respiration pathway that utilizes oxygen
cytoplasm where glycolysis takes place
fermentation oxygen is not the final electron acceptor in this pathway
where glycolysis occurs cytoplasm
what goes in glycolysis one glucose molecule
what comes out of glycolysis 2 molecules of pyruvate 4 ATP
ATP produced in glycolysis 4 (Net 2)
where the Krebs Cycle occurs mitochondrial matrix
what goes in the Krebs Cycle 2 Acetyl CoA
what comes out of the Krebs Cycle 4 CO2 2 FADH2 6 NADH 2ATP
ATP produced in the Krebs Cycle 2
where the ETC occurs inner mitochondrial membrane
what goes into the ETC 10 NADH 2 FADH2 6 O2
what comes out of the ETC 30 ish ATP
ATP produced in the ETC 30 ish
Which fermentation method can occur in animal skeletal muscles? lactic acid fermentation
Which fermentation method can occur in yeast cells? alcohol fermentation
The net production of ATP through fermentation is _____ ATP? 2
Endergonic reactions are the type of reactions that require energy before anything happens
Which of the following statements about exergonic reactions is NOT true? They release energy at their completion Energy must be added for the reaction to take place Exergonic is associated with catabolic reactions energy must be added for the reaction to take place
ATP is an important energy molecule. Structurally, it is made up of an adenine molecule, three phosphates and which of the following sugars? ribose
An orderly sequence of reactions with specific enzymes acting at each step is the definition of what? any metabolic pathway in a cell
Enzymes are proteins made in our cells to do which of the following? Effect the speed of reactions Join with a substrate to help cause a change in it Place stress on the bonds of a substrate to cause it to break apart All of the above are correct all of the above
Enzymes are defined as what kind of molecules? Catalysts Specific to the substrate Organic molecules All of the above are true all of the above
Enzyme action may be controlled by doing which of the following? Changing the pH Using inhibitors Changing the temperature All of the above all of the above
A molecule that gives up an electron in a reaction is said to be Ionized Reduced Oxidized Dehydrated oxidized
All of these terms are associated with an enzyme EXCEPT Carbohydrate Catalyst Active site Activation energy cabohydrate
competitive inhibition An inhibitor molecule is similar enough to a substrate and it binds to the active site and simply blocks the substrate from binding
noncompetitive inhibition An inhibitor molecule binds to the enzyme in a location other than an allosteric site and still manages to block the substrate
allosteric inhibition Inhibitor molecules bind to enzymes in a location where their binding induces a conformational change that reduces the affinity of the enzyme for its substrate

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
