ANT 2100 1st Edition Lecture 7 Proteins continued… I. Protein synthesis a. Transcription 1. Process of producing mRNA 2. DNA separated and gene is exposed 3. MRNA is produced by making a complimentary of a copy of gene 4. Nucleotides and their bases arranged in groups of three called codons5. Each codon is the code for an amino acid b. Translation 1. Formation of primary structure from information contained in MRNA 2. MRNA passes through and is read by a ribosome 3. TRNA carries specific amino acids to a ribosome c. Post-translational events 1. Amino acids is deleted 2. Carbohydrates added 3. Phosphate added d. Carbohydrate metabolism 1. Catabolism of glucose via glycolysis to form two pyruvic acids2. Glucose is absorb by the digestive tract 3. Fructose and galactose is turned into glucose and taken in by the liver 4. Excess glucose can be converted into fatty acids 5. Lipogenesis- production of lipids occurs in liver and adipose tissue e. Lipid/Fat metabolism 1. Fatty acids 2. Beta-oxidation (catabolism of fatty acids) 3. Turns into acetyl-CoA 4. Then into a Ketone 5. There are 3 Ketones (acetoactic acid, B-hydroxybutyric, and acetone are ketones) f. Protein metabolism 1. Protein 2. Amino acid go through oxidative deamination (catabolism of amino acids) These notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.3. Turns into ammonia 4. The liver turns the ammonia into urea II. Receptors Visual Aid Chemical The CellThe chemical binds to the receptor and cause stuff to happen. a. Specificity- binds to specific receptors b. Agonist (activator)- chemical that mimics another chemical, stimulates the action of the receptor c. Antagonist (blocker)- stops a receptor from working blocks receptor
