This enzyme uses a proton gradient to produce cell energy
ATP Synthase
Cell respiration turns glucose and oxygen into these three products...
CO₂ (carbon Dioxide) H₂O (water) ATP (energy)
This sugar is made by plants and is used by both plants and animals for energy
Glucose (C₆H₁₂O₆)
This stage of aerobic respiration generates THE MOST ATP for the cell

What type of fermentation occurs in human muscle cells?
Lactic acid fermentation
In cell respiration, LOW energy ________ is converted to HIGH energy _________ for the cell.
ADP , ATP
How do yeast contribute to bread dough rising?
Yeast undergo cellular respiration (heterotrophs) and produce CO2 as a waste product which forms bubbles in the dough and causes the dough to expand and rise
Why can PLANTS perform BOTH photosynthesis and cellular respiration?
Plants have chloroplasts AND mitochondria in their cells!!
In the first stage of Aerobic respiration, glucose sugar is broken down into TWO molecules of ...
