Bio 1404 Exam Review

• Choose the number that corresponds to an exergonic reaction.
• 1
• 2
• 3
• 4

–Answer

• 3
• In which compartment does glycolysis take place?
• Extracellular space
• Cytosol
• Mitochondrion
• Golgi apparatus

–Answer

• Cytosol
• Where does the carbon atoms in the carbon fixation stage come from?
• Water
• Soil
• Air
• Chloroplast

–Answer

• Air
• Which of these statements correspond to the Calvin cycle
• Sugar -> pyruvate -> Acetyl coA
• Sugar -> - 2 ATP -> +4 ATP
• C02 -> fixation -> reduction
• Light -> electron transport chain -> ATPase

–Answer

• C02 -> fixation -> reduction 1 / 3

SUBSCRIBE

• What is true about this reaction? NAD+ -> NADH
• NAD+ is a reducing agent
• NAD+ is being oxydized
• NAD+ is being reduced
• This reaction takes place in photosynthesis.

–Answer

• NAD+ is being reduced
• What happens in both, respiration & photosynthesis?
• glycolysis, electron transport chain, oxidative phosphorylation
• electron transport chain, chemiosmosis
• carbon reduction, NAD+ to NADH, FAD+ to NADH2
• consume water and C02.

–Answer

• electron transport chain, chemiosmosis
• What goes in the blank? Glucose-> ->Pyruvate->

A) FAD+

• 2 ATP invested

C) 6 NADPH

• Net 2 ATP

–Answer

• Net 2 ATP
• When is C02 released?
• In the calvin cycle
• between glycolysis and the citric acid cycle

• At the end of photosynthesis
• During chemiosmosis

–Answer

• between glycolysis and the citric acid cycle
• During chemiosmosis
• Protons flow against their concentration gradient 2 / 3

SUBSCRIBE

• Protons move from high pH to low pH
• From the inside of the granum to the stroma
• Along their concentration gradient

–Answer

• Along their concentration gradient
• What is true about NAD+ -> NADH
• It takes place in both, animal and plant cells
• It only takes place in animal cells
• It only takes place in plant cells
• It only takes place in eukaryotic cells

–Answer

• It takes place in both, animal and plant cells
• What is true about the electron transport chain?
• It is an exergonic process
• It moves electrons from the matrix to the intermembrane space
• It is an endergonic reaction
• It occurs in the chloroplast membrane.

–Answer

• It is an exergonic process
• Which of the following is not a way that cells can signal each other in a multi-celled

organism? (Outcome #2) (DOK 1)

• via cell- cell contact
• via hormones
• via temperature changes

–Answer

• via temperature changes
• A cell needs to make more and more of a hormone. What mechanism of cell signaling do

you postulate would accomplish this? (Outcome #2) (DOK 3)

• autocrine signaling
• paracrine signaling
