Study Notes

Asexual Reproduction in Yeast

  • Yeast is a single-celled fungus used in creating bread, cheese, and antibiotics.
  • Yeast primarily consumes sugars and starches.
  • Yeast's byproducts are carbon dioxide and alcohol.
  • Yeast reproduces asexually through budding, a process where a new cell develops from a parent cell.
  • The new cell is genetically identical to the parent cell.

Cellular Respiration in Yeast

  • Aerobic respiration occurs in the presence of oxygen, resulting in carbon dioxide, water, and energy.
  • Anaerobic respiration occurs in the absence of oxygen, resulting in carbon dioxide, alcohol, and energy.

Key Facts

  • New cells arise from pre-existing cells.
  • Yeast cells reproduce exponentially.
