Cellular Energetics Unit 3

Quiz yourself by thinking what should be in each of the black spaces below before clicking on it to display the answer.
        Help!  

Term
Definition
show any pigment in plants that can absorb light energy and pass the electrons along to the primary pigment which starts the process of photosynthesis  
🗑
Acetyl coA   show
🗑
show a graph of the rate of biological effectiveness plotted against wavelength of light  
🗑
Activation energy   show
🗑
Active Site   show
🗑
show the synthesis of complex molecules from simpler ones  
🗑
show the type of respiration through which cells can break down sugars to generate energy in the absence of oxygen  
🗑
show the process for modulating the activity of a protein by the binding of a ligand, called an effector, to a site topographically distinct from the site of the protein, called the active site, in which the activity characterizing the protein is carried out  
🗑
ATP   show
🗑
Autotroph   show
🗑
Calvin Cycle   show
🗑
show the sequences of enzyme-catalyzed reactions by which relatively large molecules in living cells are broken down, or degraded  
🗑
Catalyst   show
🗑
Cellular Respiration   show
🗑
Chemiosmosis   show
🗑
show the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar  
🗑
show the formation of ATP from ADP and a phosphorylated intermediate, rather than from ADP and inorganic phosphate, Pi  
🗑
show organisms that obtain their energy from a chemical reaction (chemotrophs) but their source of carbon is the most oxidized form of carbon, carbon dioxide (CO2).  
🗑
show a pigment that gives plants their green color, and it helps plants create their own food through photosynthesis  
🗑
show plant cell organelles that convert light energy into relatively stable chemical energy via the photosynthetic process  
🗑
show key metabolic pathway that connects carbohydrate, fat, and protein metabolism. The reactions of the cycle are carried out by eight enzymes that completely oxidize acetate, in the form of acetyl-CoA, into two molecules each of carbon dioxide and water.  
🗑
show organic compounds required by many enzymes for catalytic activity  
🗑
show a non-protein chemical compound that tightly and loosely binds with an enzyme or other protein molecules  
🗑
show the way organelles in eukaryotic cells live and work in separate areas within the cell in order to perform their specific functions more efficiently  
🗑
Consumer   show
🗑
show a 'short circuiting' of the normal z scheme of the light reaction of photosynthesis where energy that otherwise would have gone into making NADPH instead is diverted towards making more ATP.  
🗑
Denaturation   show
🗑
show A group of compounds that pass electron from one to another via redox reactions coupled with the transfer of proton across a membrane to create a proton gradient that drives ATP synthesis  
🗑
show a measure of randomness or disorder in a system.  
🗑
Endergonic Reaction   show
🗑
show proteins that help speed up metabolism, or the chemical reactions in our bodies  
🗑
Exergonic Reaction   show
🗑
show occurs to increase the change or output: the result of a reaction is amplified to make it occur more quickly  
🗑
show A saclike membrane in the chloroplasts of plant cells that is often arranged in stacks called grana and that is the site of the light reactions of photosynthesis.  
🗑
Feedback Inhibition   show
🗑
show an anaerobic process in which energy can be released from glucose even though oxygen is not available  
🗑
show the process in which glucose is broken down to produce energy  
🗑
show an organism that consumes other organisms in a food chain  
🗑
Induced Fit Model   show
🗑
show the series of biochemical reactions in photosynthesis requiring light energy that is captured by light-absorbing pigments (such as chlorophyll) to be converted into chemical energy (ATP and NADPH)  
🗑
show a series of biochemical reactions in photosynthesis not requiring light to proceed, and ultimately produce organic molecules from carbon dioxide  
🗑
Metabolic Pathway   show
🗑
show membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate  
🗑
show nicotinamide adenine dinucleotide, is a critical coenzyme found in every cell in your body, and it's involved in hundreds of metabolic processes.  
🗑
show coenzyme that functions as a universal electron carrier, accepting electrons and hydrogen atoms to form NADPH, or nicotinamide adenine dinucleotide phosphate.  
🗑
show a self-regulatory system in which it feeds back to the input a part of a system's output so as to reverse the direction of change of the output.  
🗑
show a 'short circuiting' of the normal z scheme of the light reaction of photosynthesis where energy that otherwise would have gone into making NADPH instead is diverted towards making more ATP  
🗑
Oxidative Phosphorylation   show
🗑
show chemical process by which molecules are broken down into smaller units through the absorption of light.  
🗑
Ribulose Bisphosphate   show
🗑


   

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
 
To hide a column, click on the column name.
 
To hide the entire table, click on the "Hide All" button.
 
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
 
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
