1. Which of the following would be FALSE? a) phosphatases remove the phosphate from GTP on GTP-binding proteins, turning them off. b) Protein kinases transfer the terminal phosphate from ATP onto a protein. c) Serine/threonine kinases are the most common types of protein kinase. d) A GTP-binding protein exchanges its bound GDP for GTP to become activated. I picked 'A' for #1, is that correct?

2. Which of the following sentences about GABA receptors is FALSE? a)They promote neuronal uptake of Na+. b) they inhibit synaptic signaling. c) they are ligand-gated channels. d) they are located on postsynaptic membranes

I chose 'A' for #2, is that correct?

Proteins are the workhorses of the cell, controlling virtually every reaction within as well as providing structure and serving as signals to other cells. proteins are long chains of  amino acids  , and the exact sequence of the amino acids determines the final structure and function of the protein. instructions for that sequence are encoded in  genes  . to make a particular protein, a messenger ribonucleic acid (mrna) copy is made from the gene (in the process called  transcription  ), and the mrna is transported to the  ribosome  . protein synthesis, also called  translation  , begins when the two ribosomal subunits link onto the mrna. this step, called initiation, is followed by elongation, in which successive amino acids are added to the growing chain, brought in by transfer rnas (trnas). in this step, the ribosome reads the  nucleotides  of mrna three by three, in units called  codons  , and matches each to three nucleotides on the trna, called the anticodon. finally, during termination, the ribosome unbinds from the mrna, and the  amino acid  chain goes on to be processed and folded to make the final, functional protein
