Question
2.) in electron transport, hydrogen ions and electrons from enzymes are passed from one electron acceptor or electron carrier to the next until they combine with oxygen to form h2o. What are two of the enzymes? 3.) Why would this stop electron transport?Test Chapter 23 TestItem 10 tem 10 Part A In the citric acid cycle, which of the following is true? O GDP gives a phosphate group to a molecule of ADP to form ATP O Two carbon dioxide molecules are produced for each turn of the cycle O Twelve ATP are produced for each pyruvate molecule O NADH is converted to NAD+ Submit Answers Give Up My Answers Give Up here to search
Explanation / Answer
10)
gdp is not the source for phosphorylation in citric acid cycle. Option 1 is incorrect .
2 molecules of CO2 generated for each turn of the cycle. Option 2 is correct .
10 ATP molecules are produced for each pyruvate molecule. This option is incorrect .
NAD+ to NaDH conversion takes place in the citric acid cycle. not NADH to NAD+ . So this option is also incorrect .
36)
NADH and FADH2 because they are rich source of electrons and also contains hydrogen ion for donation.
43)
If CN- binds to heme of cytochrome Fe cannot oxidize fe2+ to fe3+ and will not be transported and thus stopping electron tranfer.
