NGSS.HS-LS2-3

Electrons from the metabolism of carbs are transferred to

• reduced coenzymes (NADH and FADH2)

• not this

how many compartments are in the mitochondria?

• 1

• 2

• 3

• 4

Answer explanation

1. 1. outer membrane

2. 2. intermembrane space

3. 3. inner membrane

4. 4. matrix

Cells with higher energy need will have more mitochondria.

• True

• False

Relatively porous membrane that allows passage of metabolites and movement of phosphate, CAC components, ADP and ATP

• inner membrane

• outer membrane

similar environment to cytosol with higher proton concentration (lower pH)

• inner membrane

• outer membrane

• intermembrane space

• matrix

impermeable to ions and polar molecules and location of ETC and ATP synthase.

• inner membrane

• outer membrane

Cristae increase the surface area of the

• inner mitochondrial membrane

• outer mitochondrial membrane

location of the CAC and beta oxidaiton and amino acid metabolism with LOW proton concentration (high pH)

• matrix

• intermembrane space
