Answer the following question given this paragraph: Catabolic reactions involve breaking bonds. Larger molecules are broken down to smaller ones. For example, complex carbohydrates are broken down to simple sugars. Catabolic reactions release energy, so they are exothermic. Q: What is broken during catabolic reactions, such as the breakdown of complex carbohydrates into simple sugars? A:
OPTIONS:
- ions
- forms
- metals
- bonds

Answer: bonds

Q: Answer the following question given this paragraph: In eukaryotic cells, most of the intracellular proteins that are activated by a ligand binding to a receptor protein are enzymes. Receptor proteins are named after the type of enzyme that they interact with inside the cell. These enzymes include G proteins and protein kinases, likewise there are G-protein-linked receptors and tyrosine kinase receptors. A kinase is a protein involved in phosphorylation. Tyrosine kinase receptors bind many polypeptide growth factors, cytokines, and hormones. Once the ligand is bound, these receptors specifically phosphorylate tyrosine amino acids, activating the signal transduction process inside the cell. Q: What is named after the type of enzyme they interact with in the cell? A:

OPTIONS:
- oxygen proteins
- function proteins
- nitrogen proteins
- receptor proteins

A: receptor proteins
