Respiration w what is respiration ? cell respiration of glucose energy f ATP Kir yaror ADP+Pi equation : 21 JOOXTO bhilworks of im. Satt on 95019 auNDT a cell GLUCOSE is the main source of energy in Energy is released when glucose is broken down into ATP and stored in muscle Ils everywhere in your body. Cells that require lots of energy have lots of mitochondriagad mitochondria - • function: The site of stage 2 (pyruvic acid breakdown) of aerobic respiration. RESPIRATION is the enzyme -controlled series of reactions to break down glucose and produce energy for a cell. There are 2 types of respiration : pagsuborg bbc→→ Aerobic respiration cochon stai 11919l2m03 energy plosply Fermentation muscle contraction, sperm movement, photosynthesis, protein synthesis, etc... AEROBICA ghixoib do Aerobic respiration is the enzyme-controlled process. where glucose is broken down, in the presence of oxygen (aerobic conditions) to release energy, in the form of ATP. Carbon dioxide (CO₂) and water (H₂O) are produced as by products. A (same in animal & Glucose + Oxygen Forms a total of 38 ATP molecules. Carbon dioxide plant cells) SCUONIO + water + ATP almas There are 2 stages of aerobic respiration: Stage 1: Glucose Pyruvic acid GLYCOLYSIS 2 ADP + Pi Oxygen 2 ATP Pyruvic acid Glucose Stage 2 : PYRUVIC ACID BREAKDOWN key features Takes place in the mitochondria Oxygen is required.

FERMENTATION Fermentation is a type of respiration where an organism can't take in enough oxygen to meet the demand. Glucose is only partly broken down and only a few ATP molecules are produced. • The products of fermentation differ in animal and plant cells. fungal cells are the same as plants in this case. oppie apavą È Płopiq equations :mmopro bat bay PLANT → FUNGAL er blas snupy is goote nil Glucose ANIMAL 192000 Glucose Stage 1: WTE → Ethanol + Carbon dioxide + ATP obixoih god10) in nou pas As oxygen is not required for fermentation, the entire process takes place in the cytoplasm.
