HB2 - 1,2). Metabolism, catabolism, anabolismOutline the nutrients required by the body. Macronutrients main source for ATP generation: Complete proteins provide all nine amino anabolic metabolism refers to quizlet, incomplete missing one or more. Proteins are broken down into amino acids for absorption in GI tract. Triglycerides are the main acid. Broken down into monoglycerides and fatty acids for absorption.
Anabolic and Catabolic Metabolism Flashcards | Quizlet
One reason that protein synthesis is important is that A. Anabolic metabolism refers to A. Which of the following is an example of catabolism A.
The assembly of a cell membrane from precursor molecules B. The increase in muscle tissue with exercise C. The formation of secretory proteins in the pancreas D. The breakdown of glucose in the cytoplasm and mitochondria. Catabolism refers to A. Chemical reactions that acquire energy B.
Chemical reactions that release energy C. Synthesis of large molecules D. The formation of genetic material. Chemical reactions that release energy. An example of an anabolic reaction is A. Many monosaccharides bonding, forming glycogen B. A dipeptide breaking down into two amino acids C. Glycerol reacting with 3 fatty acid molecules to yield water and proteins D.
Glycogen breaking down into many monosaccharides. Many monosaccharides bonding, forming glycogen. In dehydration synthesis of a carbohydrate, A. Larger molecules are decomposed into smaller ones B. Monosaccharides are joined C. Water molecules bond to monosaccharide molecules D. The molecule is decomposed into carbon dioxide and water. When a sucrose molecule is decomposed to yield a glucose molecule and a fructose molecule, A. A water molecule is used. Lose H2O to form bonds; use H2O to break bonds.
Which of the following is not a characteristic of enzymes A. They are most active at temperatures above 53 degrees C. An enzyme is A. A molecule, usually a protein, that speeds the rate of a biochemical reaction by lowering the activation energy. The name of an enzyme ends in A. Which of the following best describes the interaction between an enzyme and its substrate A.
Part of the enzyme temporarily binds part of the substrate molecule. An active site of an enzyme is A. The part of an enzyme that combines with a substrate.
An important mechanism that controls metabolic pathways under physiological conditions is A. Three factors that increase the rates of enzyme-controlled reactions are the A.
Number of enzyme molecules, number of substrate molecules, and efficiency of the enzyme. Humans require vitamins in their diets because these nutrients A. A molecule that carries energy in a form the cell can use is A. ATP is important to cellular processes because it A. Provides energy for cellular work when the terminal, high-energy bond is broken.
Energy is defined as A. The ability to do work. What is the function of ATP molecules in living cells A. They capture energy from the oxidation of fuels in their high-energy phosphate bonds, and the energy is used in various cell processes. Oxidation during cellular respiration differs from burning in that respiration A. Uses enzymes to lower the activation energy. The anaerobic reactions of cellular respiration take place in the A.
Which of the following substances increases in abundance during cellular respiration A. A glucose molecule is broken down into two pyruvic acid molecules in A. In cellular respiration, A. Energy is released from molecules and is transferred to other molecules. Cytoplasm without O2 required; mitochondria with O2 required. Anaerobic reactions of cellular respiration A. Do all of the above. A molecule that is a storage form of carbohydrate is A. Which choice lists structures in order of increasing size A.
DNA replication occurs A. During interphase of the cell cycle. During DNA replication A. The DNA double helix comes apart where hydrogen bonds join base pairs, and new nucleotides are brought in, forming two double helixes. The genetic code is A. The correspondence between a sequence of three DNA nucleotides and a specific amino acid. Which of the following is not true regarding RNA A.
Transcription and translation differ in that A. Transcription produces RNA and translation producers protein. A peptide bond forms between A. Which DNA sequence can encode the amino acid sequence il-asp-see-cys-his-tyr A. Codons are part of A. Synthesis of protein stops when A.
Any of the three "stop" codons are encountered in the mRNA. The genome sequences of different individuals are A. A mutation is A. A mutation can cause disease if A. The DNA sequence changes so that one amino acid is substituted for another in a way that affects the encoded protein's functioning. In the DNA damage response A. Repair enzymes replace mismatched nucleotides in DNA.
Metabolism refers to all of the chemical reactions in a cell. Proteins are critical to metabolism because all proteins are enzymes. Catabolism builds up molecules and anabolism breaks down molecules. Releasing the energy in glucose molecules is an example of catabolism. Dehydration synthesis is catabolic and hydrolysis is anabolic. In adipose tissue, fat molecules form when fatty acid molecules and glyceroljoin by hydrolysis.
Enzymes are proteins that promote specific chemical reactions. A metabolic pathway is a particular sequence of enzyme-controlled reactions.
A rate-limiting enzyme usually acts at the end of a metabolic pathway. An ATP molecule consists of an adenine, a ribose, and three phosphates. Oxidation of glucose is important because it releases energy. During the aerobic reactions of cellular respiration, pyruvic acid reacts to form glucose. The aerobic reactions of cellular respiration occur in the mitochondria.
The electron transport chain is a series of enzyme complexes that pass electrons, releasing energy that is used to phosphorylate ADP to ATP on the inner mitochondrial membrane.
If you eat too many carbohydrates, they can be store as fat. All of the genetic information in a cell is a genome. Genetic information is contained in protein molecules and is passed from one parent to another. The portion of a DNA molecule that contains the genetic information for making a protein is called a gene.
In DNA replicsrion, the two halves of the double helix separate and enzymes place A, C,G G, and U nucleotides opposite their complements, forming two double helixes from one. The genetic code is the correspondence between DNA sequence and amino acid sequence of a protein.
