What role does NAD+ play in cellular respiration?

It acts as a electron acceptor and carries electrons to the ETC which creates ATP through ATP synthase.

100

Fill in the blanks

In the Mitochodria the locations of where the krebs cycle occurs is in the________and the electron transport chain is in the________.The glycidic pathway occurs in the_________.

Matrix of Mitochodria, the cristae membranes, and cytoplasm.

100

What is the primary function of the electron transport chain?

A. For oxygen to oxidized 

B.so NAD+ can be recycled for the glycidic pathway 

C.so that electrons can pass through the ETC for H20 to be created

D.to produce a proton gradient, which is utilized to produce ATP through oxidative phosphorylation

D.to produce a proton gradient, which is utilized to produce ATP through oxidative phosphorylation

100

Is the krebs cycle aerobic or anaerobic?


Aerobic

100

Which part of cellular respiration produces 2 ATP, 2 NADH, and creates 2 molecules of pyruvate?

Glycolysis 

200

What fermentation related to glycolysis?

Fermentation is a anaerobic process that regenerates NAD+ to continue producing ATP

200

What part of the Mitochodria is really permeable to allow small molecules  containers porins that allows large molecules which exchanged with the cytoplasm 

Outer membrane

200

Why is oxygen needed in aerobic respiration?

Oxygen is needed to be the final electron acceptor.

200

What products are produced during the krebs cycle and what is the yield?


6 NADH molecules.

2 FADH₂ molecule.

1 GTP molecule.

4 CO2 

2ATPs

200

What is the full name of energy currency in cellular Respiration 

adenosine triphosphate(ATP)

300

What is the first phase called for in the glycolytic pathway called and why is it call this


Energy investment phase and its a requirement to transfer energy transfered into the form ATP


300

What part of the Mitochodria increases the surface area for cellular respiration?

A)inner membrane 

B)outer membrane 

C) cristae 

D)ATP synthase

C) cristae 

300

What are three things produced in the electron transport chain

ATP,NADPH, and oxygen 

300

What are the inputs and outputs of the krebs cycle 

Acetyl CoA, water, NAD+, FAD, and ADP + Pi. The outputs are CO2, NADH, FADH2, ATP, and CoA.

300

What is term for when Ions have movement across the electro chemical gradient which allows hydrogen ions to pass through ATP synthase.

Chemiosis 

400

Dihydroxyacetone phosphate is quickly and reversibly changed to ___________

A) Glyceraldehyde 3-phosphate

B) pyruvate 

C)Dihydroxyacetone phosphate

D)Fructose 1,6-bisphosphate


A) Glyceraldehyde 3-phosphate- it's converted by triose phosphate isomerase

400

Which part of the cell does oxidative phosphorylation take place?

Inner Mitochodria membrane 

400

What is the purpose of complexes 1 and 2?

Complex 1  transfers electrons from NADH. Energy is released, which is used to pump protons (H+) from the mitochondrial matrix into the inner membrane

Complex 2 oxidize the FADH2 back into FAD and move electrons across the ETC witha series of iron-sulfur clusters and onto ubiquinone

400

It's a temporary step in glycolysis  where a 3 carbon molecule is created during oxidation of G3P. transfers a phosphate group from 1,3-BPG to ADP, which forms ATP.

1,3 biphosphoglycerate

500

What are the main enzymes that are used in the glycolytic pathway and what are their functions?



Hexokinase- catalyzes the phosphorylation of glucose to glucose 6 phosphate 

Phosphofructokinase- catalyzes the transfer of a phosphate group from ATP to fructose-6-phosphate, forming fructose-1,6-bisphosphate and ADP

Pyruvate Kinase- converts phosphoenol  pyruvate to pyruvate 


500

Which of the following best describes complex IV in the electron transport chain?

A)Complex IV consists of an oxygen molecule held between the cytochrome and copper ions. The electrons flowing finally reach the oxygen, producing water.

B)Complex IV contains a molecule of flavin mono nucleotide and iron-sulfur clusters. The electrons from NADH are transported here to coenzyme Q.

C)Complex IV contains cytochrome b, c and Fe-S. Here, the proton motive Q cycle takes place.

D)Complex IV contains a membrane-bound enzyme that accepts electrons from FADH2 to make FAD. This electron is then transferred to ubiquinone



A)Complex IV consists of an oxygen molecule held between the cytochrome and copper ions. The electrons flowing finally reach the oxygen, producing water.
