The final net products of ________ are 2 molecules of ATP and 2 NADH.
glycolysis
The concentration of ATP controls the rate at which the ________ step of the citric acid cycle
occurs.
first
In the absence of ________, some organisms are able to convert glucose to energy via
fermentation.
oxygen
The two main types of anaerobic cellular respiration are lactic acid fermentation and
________.
alcohol fermentation
,Lactic acid generated by fermentation in muscles ________.
is sent to the liver for conversion back into pyruvic acid
Which of the following statements accurately describes what happens to electrons during
an oxidation-reduction reaction?
One reactant will lose electrons while the other reactant will gain electrons.
Chemiosmosis
a process of ATP production in cellular metabolism, is used to generate 90 percent of the
ATP made during glucose catabolism and is also the method used in the light reactions of
photosynthesis to harness the energy of sunlight.
ATP can be used over and over to release and store energy just like the battery found inside
of a cell phone. Which molecule of ATP broken off to release energy and rejoins to store
energy?
Phosphate
The most direct method of phosphorylation is ________ phosphorylation.
substrate-level
, A living cell cannot store large amounts of ________ because it would create a destructive
increase in heat.
free energy
The atom that accepts electrons in a redox reaction is the ________.
oxidizing agent
________ reactions comprise most of the chemical reactions involved in cell metabolism.
Oxidation reduction or redox reactions
The passing of electrons from one molecule to another in a cell is are known as ________.
redox reactions
Gerald is explaining to his daughter how a plant makes energy through the process of
photosynthesis. When explaining photosynthesis he gets the products and reactants mixed
up. Which of the following statements has Gerald gotten incorrect?
Photosynthesis takes in the gas that we breathe out called oxygen and after photosynthesis
takes place takes place the plant releases carbon dioxide, the gas that we need to survive.
Plants all have pigments present in their cells that allow them to thrive in different
environments. How do pigments help to make this possible?
pigments allow for different plants to absorb different wavelengths of light.
