- Why do cells metabolize carbohydrates?arrow_forwardAlanine, cysteine, glycine, serine, and threonine are amino acids whose breakdown yields pyruvate. Which, if any, of the remaining 15 amino acids also do so?arrow_forwardIs it possible for fatty acid chains to be broken down to produce ATP in the absence of oxygen?arrow_forward
- When simple monosaccharides are linked together into larger oligosaccharides by the process of dehydration synthesis, what other molecule is created?arrow_forwardInsulin, a hormone release in large part due to carbohydrate consumption and subsequent presence in the blood stream, will influence protein synthesis. Why does it make physiological sense for this overlap between the metabolism of two different classes of molecules?arrow_forwardWhat type of reaction takes place when two amino acids join together?arrow_forward
- The normal enzyme required for converting sugars into glucose is present in cells, but the conversion never takes place and no glucose is produced. What could have occurred to cause this defect in a metabolic pathway?arrow_forwardIn enzymatic hydrolysis, the bonds of starch are broken to obtain glucose. How does this process work? What kind of reaction occurs?arrow_forwardWhy are some amino acids called essential?arrow_forward
- Wasting is one of the characteristics of HIV / Aids, caused by increased metabolic activity. Untreated patients quickly lose up to 10% of their body weight, with loss of muscle mass contributing most. What happens to the amino group of amino acids that are broken down in the muscles? Fully explain the process of amino acid degradation in the muscle up to urea production in the liver.arrow_forwardWhenever a person consumes dairy products, they utilize lactase enzymes to break down the disaccharide carbohydrate, lactose into monosaccharides: galactose and glucose. Overtime, these enzymes become worn and need to be replaced. The following DNA sequence contains the information needed to build more lactase enzymes: 3’ – ACCTCTTACTTTTATATATAGGGAAGACTAATTGTC – 5’ 5’ – TGGAGAATGAAAATATATATCCCTTCTGATTAACAG– 3’ Which strand is the template strand?arrow_forwardWhy is the conversion of lactic acid from theblood into glucose in the liver in an organism’s best interest?arrow_forward
