Multiple Choice Questions

Fuel molecules are broken down further in glycolysis and the ctric acid cycle (Krebs cycle)
  • how food molecules reach the body's cells and fuel cellular respiration. Step 4
  • Respiration extracts energy from pyruvate that is wasted in fermentation.
  • how food molecules reach the body's cells and fuel cellular respiration. Step 3
  • kinetic energy that is released as hydrogen ions diffuse down their concentration gradient
How much usable energy is produced by lactic acid fermentation?
  • Hydrogen ions from the matrix are pumped into the intermembrane space, then flow back into the matrix through ATP synthase.
  • This process uses energy captured from electrons flowing to oxygen to produce most of the ATPs in cellular respiration.
  • zero ATP and zero NADHFermentation does not produce usable energy. It actually wastes the energy in NADH to return it to NAD+ for use by glycolysis.
  • To use energy from the passing of electrons in electron carriers into a high concentration of hydrogen ions
Eating food provides fuel and building blocks for your body
  • To use energy from the passing of electrons in electron carriers into a high concentration of hydrogen ions
  • how food molecules reach the body's cells and fuel cellular respiration. Step 3
  • how food molecules reach the body's cells and fuel cellular respiration. Step 2
  • how food molecules reach the body's cells and fuel cellular respiration. Step 1
A line of mutated yeast cells, called Wee mutants, has no mitochondria. Their name comes from the fact that these cells are very small compared to other yeast cells. Which energy-harvesting processes can Wee mutants perform?- glycolysis, fermentation, and respiration - glycolysis and fermentation - cellular respiration - glycolysis - the aerobic processes
  • glycolysis and fermentationThese processes occur in the cytoplasm.
  • because lactic acid fermentation doesn't produce a gas
  • electron transport.
  • This process splits glucose in half and produces 2 ATPs for each glucose.
After food is broken down in the digestive system, it transported to cells via the circulatory system
  • glycolysis → acetyl CoA → citric acid cycle → electron transport chain
  • Two were lost in acetyl CoA formation and four were lost in the Krebs cycle.
  • how food molecules reach the body's cells and fuel cellular respiration. Step 2
  • how food molecules reach the body's cells and fuel cellular respiration. Step 4
