Biological Molecules Lipids Carbohydrates Nucleic Acids Portions
# parts of the Cell Theory basic unit of life all living organisms have cells
Prokaryote single stranded DNA OG cell no nucleus no organelles (EXCEPT RIBOSOMES) ALL UNICELLULAR ex bacteria
Eukaryote double stranded DNA more complex nucleus has organelles multi or unicellular plants or animals
Chloroplast green organelles that make the food FOUND ONLY IN PLANTS
Chlorophyll pigment inside chloroplast
Mitochondria organelle that releases energy from food POWERHOUSE OF A CELL

Endoplasmic Reticulum folded membranes that move proteins around a cell HIGHWAY
Golgi Bodies sort and package proteins MAIL
Vacuoles stores water,food , waste
Lysosomes digest food and breakup the cell when it dies

Carbohydrates store energy and sugar
Protein made up of amino acids
6CO2 + H20 + light ----> c6h12o6 + 6o2 photosynthesis
602+ c6h12o6 ---> 6co2 + 6h2o + 36 ATP cellular respiration
Steps for Cellular Respiration 1. Glycolysis 2. Krebs Cycle 3. ETC
How do cells create energy without oxygen ? 1. Alcoholic Fermentation 2. Lactic Acid
Alcoholic Fermentation occurs in bacteria and yeast process occurs in baking and brewing glucose - ethyl alcohol + carbon dioxide = 2 ATP
Lactic Acid occurs in muscle cells produce during rapid exercise when the body cannot produce enough oxygen glucose - lactic acid + carbon dioxide = 2 ATP
