QuestionAnswer
all of the chemical reactions of the cell are called? metbolism
the breakdown of peptidoglycan to N-acetylmuramic acid, N-acetylglucosamine and peptides is an example of? catabolism
enzymes are? proteins that function as catalysts
formation of peptide bonds between amino acids to build a polypeptide would be called? anabolism
an apoenzyme containd the active site
a holoenzyme is a cobination of a protein and one or more substances called cofactors
important components of coenzymes are vitamins
enzymes that function at boiling water temps. or other harsh conditions would be termed? extremozymes
enzymes that are produced only when substrate is present are termed induced enxymes
enzymes that catalyze removing electrons from one substrate and adding to another are called oxidoreductases
when enzyme action stops due to build up of end product this control is called negative feedback
most electron carriers are coenzymes
exergonic reactions occur during aerobic cellular respiration
in the cell energy released by electrons is often used to phosphorylate ADP
in addition to electrons, which of the following is also involoved in electron transfer hydrogen protons
The most likely place where an exoenzyme participates in a chemical reaction is? outside the cell
all of the following are exoenzymes except ATP synthase
all of the following pertain to glycolysis, except it: degrades glucose to co2 and h2o
the formation of citric acid from oxaloaxetic acis and an acetyk group begins kerbs cycle
the step involving ATP , hexokinase, and the phosphorylstion of glucose to glucose-6-phosphate is: an example of substrate-level phosphorylation
during aerobic cellular respiration, the final electron acceptor is oxygen
which of the following is not involved in the step that occurs btwn glycolysis and TCA cycle? pyruvic acid accepts electrons from NADH
in bacteria cells, the electron transport system is located in the : cell membrane
in which pathway is the most NADH generated? Krebs cycle
the reactions of fermentation function to produce ____molecules for the use of glycolysis NAD
during which of the phases of cellular respiration is the majority of of ATP formed electron transport
in bacterial cells which glucose is completely oxidized by all the pathways of aerobic cellular respiration how many ATP are generated 38 ATP
when Glucose is broken down by glycolysis durimg bacterial fermentation how many ATP are generated 2 ATP
Each NADH that enters the electrom transport system gives rise to ____ATP 3 ATP
as the electron transport carries shuttle electrons, they actively pump____into the outer membrane compartment setting up a concentration gradient called he proton motive force hydrogen ions
mixed acid fermentation produces acids plus co2 and h2 gases
anaerobic cellular respiration untilizes an electron transport system
each FADH2 that enters the electron transport system gives rise to ___ ATP 2
in Anaerobic respiration all of the following can serve as the final electron acceptor , except: oxygen
enteric bacteria commonly occupy the human intestine and primarily produce CO2 and H2 gases
the process of alcoholic fermentation produces alcohol and carbon dioxide
cyanide will cause rapid death in human because it: blocks cytochrome c oxidase
why is cyanide harless to some bacteria they lack cytochrome C oxidase
fatty acids can be metabolized by entering the TCA cycle
enzymes that are regularly found in a cell are termed constitutive enzymes
when amino acids are deaminated , they can be used as a source of glucose
in eukaryotes, glycolysis takes place in the? in the cytoplasm
in eukaryotes the Krebs cycle takes place in the in the mitochondia
photosynthesis is responsible for producing >50% of earths oxygen. during photosynthesis inorganic ___ is fixed into organic compunds like ___without the help of sunlight CO2, C6H12O6
in the eukaryote , the repiratory chain is located in the___whereas the majority of ATP is produced by the repiratory chain in thr ____of a prokaryote mitochondria, outer membrane space
