Chapter 3 bio
| Question | Answer |
|---|---|
| Explain the difference between organic and inorganic compounds and how they relate to living things | Organic- contained in carbon; in living things Inorganic- do not have carbon |
| What's the difference between ATP and ADP | ATP- has three phosphate groups ADP- has two phosphate groups ATP has more energy |
| What is an isomer | Same chemical formula but different structure |
| Name two foods that contain high amounts of protein | Meat, eggs, nuts, beans, peanut butter |
| What is it called when two amino acids are joined together | Dipeptide |
| Why is carbon used so often in living things | Can form up to four covalent bonds bonds well with other elements occurring in life can form single, double, or triple bonds |
| Does a hydrolysis reaction take in energy or release it | Releases energy |
| What is the monomer for carbohydrates called | Monosaccharide |
| Give three examples of things found in living organisms that are made of proteins. | Enzymes, hormones (insulin), horns, nails, hair (keratin), muscles |
| Explain the difference between the lock and key model and the induced fit model for enzymes | Lock and Key- enzymes fit perfectly with the substrate Induced fit- the enzyme changes shape to fit the substrate |
| List the four functional groups and their formulas | Hydroxyl - OH Carboxyl - COOH Amino - NH2 Phosphate - PO4 |
| Draw the ATP cycle and label what is happening. | ATP loses the 3rd phosphate and releases energy. Now that it has only 2 phosphates, it is ADP. ADP then gets energy from food and the 3rd phosphate rejoins creating ATP |
| What are the three monosaccharide isomers? | Glucose Fructose Galactose |
| What is the monomer for proteins? | Amino acids |
| What is a condensation reaction and how does water relate to it? | Joining monomers to form polymers by losing H2O |
| What are the elements found in carbohydrates and in what ratio | 1 Carbon : 2 Hydrogen : 1 Oxygen |
| Many monosaccharides linked together form a ... | Polysaccharide |
| How many different amino acids are there? | 20 |
| What does it mean when an enzyme is denatured? | Destroyed |
| Does a condensation reaction take in energy or release it? | Takes in energy |
| What is a disaccharide? | Two monosaccharides joined together |
| What are our three examples of polysaccharides? | Starch Cellulose Glycogen |
| What is the name of the bond found in between amino acids? | Peptide Bond |
| What is a hyrolysis reaction and how does it relate to water? | Polymers split into monomers by adding H2O |
| What are the elements that are found in proteins? | Carbon Hydrogen Oxygen Nitrogen |
| What are the two ways an enzyme can become denatured? | High temperature & pH |
| Carbohydrates are our main source of... | Energy |
| What are the three disaccharides? (Include the monosaccharides that they are made up of) | Glucose + Fructose = Sucrose Glucose + Galactose = Lactose Glucose + Glucose = Maltose |
| What are the two main functions of proteins? | Structure & defense |
