Bio 93: Lecture 15 Cellular Respiration questions with
verified answers
A drug that specifically inhibits ATP synthase will?? Ans✓✓✓ Increase
the pH differences across the inner mitochondrial membrane.
Cellular repiration Ans✓✓✓ proteins, carbohydrates, and fats can be all
used as fuel for cellular repiration, relocation of electrons from food to
O2, released energy used to synthesize atp.
Cellular Respiration Controlled Explosion Ans✓✓✓ occurs in stages:
An electron transport chain breaks the "fall" of electrons in this reaction
into a series of smaller steps an stores some of the released energy in a
form that can be used to make ATP (rest of energy released as heat)
Going in: NADH, 2H+2e-, ATP produced, H20 comes out.
Cellular respiration generates how many ATP/ glucose? Ans✓✓✓ 32!!
Cells generate a bit of ATP through glycolysis, some through citric
cycle, but most of it through oxidative phosphorylation in electron
transport chain and chemiosmosis.
Cellular respiration refers to?? Ans✓✓✓ catabolic reactions (exergonic,
energy releasing process) used to generate ATP. It is the relocation of
electrons from food to oxygen, released energy is used to synthesize
ATP (glucose in humans, sucrose in plants)
, Chemiosmosis (oxidative phophorylation) in the inner mitochondrial
membrane Ans✓✓✓ stage 3 of cellular respiration: it is a passive
transport
-ATP synthase.
Allows passive transport of H+ back to matrix
-every three protons turn ratchet like structure and that mechanical
process allows phospahte to attatch to ADP+Pi to form ATP
(chemiosmosis)
Chemiosmosis is... Ans✓✓✓ an energy coupling mechanism used to
generate ATP
Defects in mitochondrial function Ans✓✓✓ degenerative diseases,
cancer, aging, muscle weakness, metabolic dysfunction.
Muscle cells use a lot of ATP, if you have a defect in mitochondria your
muscles will be weak.
First Stage of Cellular respiration Glycolisis Ans✓✓✓ happens in the
cytosol, Glucose goes in, and pyruvate comes out.
It is a substrate level phosphorilation
How does transfer of electrons generate energy? Ans✓✓✓ An electrons
potential energy is dependent upon how far away it is from the nucleus.
The further shells contain the highest level of energy, the shell nearest to
the nucleus has the least potential energy. When the electron moves
further from the nucleus it absorbs energy, when it falls back, it looses
energy, releasing it as heat.
