What is the formula for cellular respiration? MONDAYS essential question (14)
Write a paragraph describing how energy goes from the SUN to ATP. Use these words in your paragraph: energy; sun; capture; autotroph; heterotroph; sugar; ATP; mitochondria; chloroplast
But what happens when there is no oxygen present?
Glycolysis C-C-C-C-C-C C-C-C Krebs Cycle ETC Only Glycolysis can occur O2O2
Fermentation Occurs when O 2 is NOT present AKA anaerobic respiration Two types: Lactic Acid fermentation (muscle cells) Lactic Acid fermentation (muscle cells) Alcoholic fermentation (yeast) Alcoholic fermentation (yeast) Nets only 2 ATP (instead of 36) Nets only 2 ATP (instead of 36)
