Biosynthesis and Breakdown Carbon/Energy Tracing Project

Biosynthesis ATP provides energy for biosynthesis reactions in cells Biosynthesis reactions form larger, more complex molecules from less-complex molecules Ex: starch from glucose Biosynthesis helps organisms to grow and maintain their structure Definition provided by definition bing.com biological production of chemical substances: the synthesis of chemical substances as the result of biological activity

Biosynthesis and Breakdown Metabolism: all chem. activities & changes that take place in the cell/organism All chem rxns in a cell are 2 types: Synthesis (biosynthesis): build up larger more complex molecules Breakdown/decomposition (decomp) rxns: break down larger molecules into smaller

Examples of Biosynthesis and Breakdown Build proteins from amino acids, which then build tissues, such as muscles and blood from proteins Breakdown: Cellular respiration, releases E & that E is provided from food

Importance of Food Provides E Organic Molecules for making sugar, amino acids, other compounds (cmpds) W/O Organ. Cmpnds cells could not repair or create new cells Photosynthesis provides food for producers How do heterotrophs get their food?

Digestion Digestion: breaking dwn larger molecules into smaller, simpler molecules Enzymes help break down of food Found in mouth, stomach, small intestine Speed up reactions Final digestion occrs in sm. Intestine

Sandwich process through digestion Contains: Carbs, proteins, fats sugar, amino acids, fatty acids These organic molecules then pass thru sm. Intest. Cell membrne to blood stream From blood stream go into cells

Conversions Compounds Converted to Fats: Proteins: 3-C molecule and fatty acids- which enter Krebs Amino acids

Whether a protein, carb, or fat, each organic molecule must be synthesized from the matter the organism takes in Then it must be broken down so that the organisms can use the necessary organic molecules and energy

Biosynthesis: Decomposition: Additional Info From Mz. R… Metabolism There are 2 types of metabolism: biosynthesis and decomposition. Biosynthesis: Builds up (synthesizes) new, larger, more complex molecules such as starch or DNA, proteins, build tissue and blood, etc. Consumes free energy Enables organisms to grow and maintain structure. Decomposition: Larger molecules break down into smaller ones, such as glycogen to glucose, and glucose into CO2 & water. Energy becomes available.

Where do plants get the energy they need to survive? Photosynthesis converts light energy into chemical energy stored in glucose.

What do plants do with the glucose they create during photosynthesis? So… what is the source of the mass increase in plants during their growth? CO2 + H20 Growth (cellulose, proteins, lipids) biosynthesis photosynthesis breakdown Cellular Respiration (energy) sugars biosynthesis Storage (starch)

Where do animals get the matter ad energy they need to grow and survive? Carbohydrates, Fats, Protein biosynthesis Growth (proteins, lipids) digestion Organic molecules Cellular Respiration (energy) breakdown Glucose, Amino acids, Fatty acids biosynthesis Storage (glycogen, lipids)

Sun Worship How does Energy and Matter flow through an Ecosystem? Autotroph (producer) Heterotrophs (consumers)
