What is chemical digestion?. Changing big nutrient molecules into their smaller building blocks REQUIRES ENZYMES Example: Proteins broken down into amino acids. Proteins and amino acids are different substances. Where does chemical digestion occur and name the enzyme found in each location.

All Living things- grass, trees, birds, dogs, cats, gorillas, monkeys, bugs, etc etc.
Catalysts are things that speed up reactions
Enzyme + substrate --> enzyme + product
*** the substrate is what is broken down into product (example: H202 broken into H20 and O2
NO. Enzymes are never used up and are not changed from reactions.
ONE! Enzymes are specific, they only attach to one substrate. Just like a key only goes with one lock.
Raw liver. Liver has enzymes in it. Cooked liver means the liver was in heat. Heat causes enzymes to denature which means they lose their shape. Enzymes must have an exact shape (like a key) to work
pH (acidity and basic) and temperature. Enzymes like to be in a certain range. If enzymes are in environments that are too hot, too cold, too acidic or too basic they won’t work as well and might not work at all
Catalase (hydrogen peroxidase) is an enzyme. All enzymes are found in living things. So they would be found in: raw liver and cooked liver
Mouth then esophagus then stomach then small intestine then large intestine then rectum then anus
Carbohydrates, lipids (fat), protein
They are not nutrients because they do not have calories
They are absorbed in the large intestine
Esophagus, liver, gallbladder, pancreas, large intestine, rectum
Mouth (because in mouth ONLY carbs are broken down into simple sugars by amylase)
Small intestine (because carbs are broken down into simple sugars by amylase; proteins are broken down into amino acids by protease and lipids broken down into fatty acids by lipase)
Stomach because enzyme pepsin is made by stomach
NO; it breaks down fats by mechanical digestion. It takes big lipids (fats) and turns them into smaller pieces of lipid (fat)
Mouth and stomach
They lower the energy needed for the reaction to start (enzymes lower the activation energy)
Proteins, lipids, carbs
1 enzyme for every substrate
They are opposites. The products of one are the reactants of the other
Organisms that have chloroplasts- autotrophs - trees, grass. Flowers, plants, etc.
Krebs and Electron transport chain (because aerobic means requires oxygen)
Krebs and electron transport chain
Glycolysis makes 2 ATP 2) kreb s makes 2 and 3) electron transport chain makes 34 ATP
Instead of the krebs cycle and electron transport chain, glucose is changed into lactate (lactic acid)
Plant cells. In the chloroplasts
Animal and plant cells. All living things do respiration! Mitochondria
Carbon dioxide, 38 ATP, water
Temperature, carbon dioxide concentration and light intensity
Carbon dioxide, sun energy, water
Glucose and oxygen
Electron transport chain
Glycolysis gives 2 ATP
Krebs cycle gives two
Electron transport chain gives 34
Goes in : Glucose (C-C-C-C-C-C) a 6 carbon molecule is split into 2. Each new molecule C-C-C is called pyruvate
Glycolysis, krebs, and electron transport chain
No oxygen available, glycolysis keeps repeating over and over
Glycolysis, krebs and electron transport
None. Chloroplasts is for photosynthesis. Respiration occurs in mitochondria
