krebs and ETC Flashcards
Acetyl CoA initially binds with a four-carbon molecule called ______________, releasing CoA and forming citrate in the process.
OXALOACETATE
Which among the following proteins involved in ETC is not a monotropic protein?
A. coenzyme Q
B. Cytochrome C
C. Complex three
D. Complex two
B. Coenzyme Q
α-ketoglutarate + Coenzyme A —> _____________ + NADH+ + CO2
Succinyl CoA
What is the chemical reaction that happens in the formation of fumarate?
FAD is converted into FADH2
What is the enzyme that converts citrate into isocitrate?
Isomerase
After the electrons are passed from one protein to another, hydrogen will eventually move towards the inside of the mitochondrial matrix because of the gradient between the two spaces. Hydrogen will pass through an enzyme that will in turn use the energy to manufacture ATP from ADP. What kind of transport mechanism is evident in this scenario?
Primary Active Transport
Formation of Acetyl Coenzyme A creates the following except?
a. Acetyl Coenzyme A
B. NADH+
C. Coenzyme A
D. Carbon dioxide
D. Carbon Dioxide
Given that 2 Acetyl CoA enters the Kreb Cycle, how many NADH+ are created?
6
What chemical process uses oxidative phosphorylation to create ATP?
ETC
What enzyme is used by the end of chemiosmosis to produce ATP?
ATP synthase
Why is the Kreb Cycle called the Citric cycle alternatively?
Because citric acid is the first product of the Kreb Cycle
Where does the Kreb Cycle occur?
Mitochondrial Matrix
GTP stands for
Guanosine triphosphate
In the formation of α-ketoglutarate which among the following choices is one of its by-products?
CO2
Coenzyme Q(CoQ) is also known as
ubiquinone
