The correct option is this: STORING INGESTED FOOD AND PARTIALLY DIGESTING MACRO MOLECULES.
During the digestive process, the stomach secretes acid and enzymes which digest the food in the stomach. The stomach muscles contract periodically in order to churn up the food and ensure digestion, thus turning the food to chyme. When the stomach has done its part in digestion, the chyme will be passed to the small intestines through the pyloric sphincter.<span />
Answer:
a. True
Explanation:
Ribosomes are ribonucleoprotein complexes composed of RNA and proteins, which have two main roles 1-decode the message of the messenger RNA (mRNA) molecule and the formation of peptide bonds in the protein. For this purpose, each triplet of nucleotide bases or 'codon' in the mRNA sequence is used to assemble specific amino acids in the nascent polypeptide chain. Although different, both prokaryotic ribosomes and eukaryotic ribosomes are composed of two subunits: one small subunit that decodes the mRNA into a specific amino acid chain, and one large subunit that forms the peptide bonds in the polypeptide chain. Each ribosomal subunit is in turn composed of ribosomal RNAs and proteins. These ribosomal RNAs act as scaffolds by combining with proteins that assemble into ribosomes (i.e., small and large ribosome subunits).
