The answer to this question would be hydrolysis
There is amylase enzyme inside saliva that will break down starch into maltose sugar. Maltose is the sugar that <span>causing </span>the sweet sensation in the tongue. Since it will take for the reaction to happen, the sweet taste only appears after a few moments after you chewing the bread.
The reaction that was catalyzed by amylase is hydrolysis.
Germ layer is a primary layer of cells found in the embryo. The three primary germ layers that generate most of the cells in the developing mammalian forelimb are ectoderm, mesoderm and endoderm.
Ectoderm forms the outer component of a mammalian body such as skin, hair, etc. Endoderm forms the inner layer that comprises of the linings of digestive system, lungs and thyroid. Mesoderm is the middle layer that forms the skeletal system, heart, etc.
Neural tube is generated by the inward folding of the ectoderm. This process is called neurulation. Ectoderm also forms neural crest.
I think The second step of cellular respiration is the Kreb's cycle and it occurs in mitochondrial matrix.
First step of cellular respiration is glycolysis and it occurs in the cytoplasm of a cell.
I am not really confident about my answer.
If I am wrong please correct me. <span />
