bio/health cellular respiration review

What is cellular respiration?

• how fungi and bacteria respire

• how plants breathe

• the process by which ATP is created

• the process by which ATP is released into the air

Which processes create amounts of ATP?

• Krebs cycle

• glycolysis

• ETC

• all of them

With oxygen, more ATP will be created.

• yes!

• no, ATP does not require oxygen to be created

1 mol of glucose = (a)   mol of ATP

Enzymes speed up chemical reactions.

• no! they actually slow down the chemical reactions so that our body can adapt to the changes

• yes! enzymes are catalysts that help speed up chemical reactions

The active site of the enzyme MUST perfectly match the shape of the substrate, otherwise a new product cannot be formed.

• no, the active site of the enzyme can shape itself into whatever shape the substrate is in

• yes, they must be a perfect fit

Respiration works best when there is (a)   , high pH levels if in water, and room temperature environments.

The mitochondria is...

• the powerhouse of your brain

• the cell structure where cellular respiration occurs

• where your mom lives

• the molecule where cellular respiration takes place

(bonus qn hehe) choose the option that has the correct equation for cellular respiration! (assume the arrows are all cellular respiration)

• 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂

• CO₂ + H₂O → C₆H₁₂O₆ + O₂

Aerobic processes do not require oxygen. Krebs cycle is one such example.

• both statements are true.

• both statements are false.

• aerobic processes DO require oxygen, and krebs cycle does not; krebs cycle is NOT an aerobic process

• aerobic processes do not require oxygen, but krebs cycle does and is considered an aerobic process
