Which of the following occurs in glycolysis (select all that apply)?

1

Where does in the cell glycolysis occur?

1

Which of the following occurs in acetyl CoA formation and the CAC?

Make 10 electron carriers

Start breaking down glucose

Finish breaking down glucose

Start pulling hydrogen ions and electrons off of glucose

Finish pulling hydrogen ions and electrons off of glucose

Make 2 ATP

Make 6 carbon dioxide molecules

1

Where does acetyl CoA formation and the CAC occur?

Cytoplasm

Starts in the cytoplasm and ends in the matrix

Only in the matrix

Across the inner membrane

1

Which of the following are steps in the Electron Transport Chain (select all that apply)?

The spinning of ATP synthase allows it to attach phosphates on to ADP molecules to make ATP

Oxygen combines with hydrogen ions and electrons to become water, opening ATP synthase

A concentration gradient is made

Hydrogen ions move through ATP synthase into the matrix causing it to spin

Electron carriers drop off hydrogen ions and electrons

Electrons fuel the protein pumps and allow them to pump hydrogen ions into the intermembrane space

1

The electron transport chain is located/occurs across the ...

1

Is the process of pumping hydrogen ions into the intermembrane space passive or active transport?

Passive

Active

1

What fuels the process of pumping hydrogen ions into the intermembrane space?

1

What does oxygen do in the ETC (select all that apply)?

Physically combines ADP and phosphates

Breaks down glucose

It triggers the ATP synthase to open

It combines with hydrogen ions and electrons to become water

1

Is the process of hydrogen ions moving back into the matrix (through ATP synthase) passive or active transport?

Passive

Active

1

How many water molecules are produced in the ETC?

1

The following questions are all free response questions. Once you answer each question it will automatically mark them as "wrong" because you haven't written exactly what I wrote. Once you click submit compare your answers to mine (they should show up after you click submit). Be thoughtful in your answers (think about them as practice test questions). I wrote 4-9 sentences in my sample answers for each question.

1

In your own words: Carefully explain the process of Glycolysis.

1

In your own words: Carefully explain the process of Acetyl CoA Formation and the Citric Acid Cycle.

1

In your own words: Carefully explain the process of the Electron Transport Chain.

1

Explain the role of concentration gradients in the Electron Transport Chain.

1

Explain the relationship between Cellular Respiration and passive and active transport.

1

Explain how the dam analogy relates to Cellular Respiration (in this explanation state what each component of the analogy is - the water, the wall, the generator).

1

Throwback to the organelles unit at the beginning of the year - how does photosynthesis and cellular respiration relate? This is a tricky one, and we will talk about it but try your best.
