Answer:
B The hydrolysis of gelatin provides amino acids for the cell.
D. The hydrolysis of gelatin allows the bacteria to travel deeper into tissue
Step-by-step explanation:
Gelatin is a type of food material which is extracted from collagen that is present in different body parts of animals. When gelatin is broken down into simpler substances, amino acids are produced. Valine, proline, arginine, alanine, lysine and glycine are the amino acids which are extracted from gelatin. Some bacteria liquifies gelatin and starts spreading through the living host cell.
