The subtrate will no longer fit within the enzyme because the heat will cause the enzyme to denature (deform).

<h3>Enzyme </h3>

Proteins called enzymes serve as biological catalysts (biocatalysts). Chemical reactions are sped up by catalysts. Substrates are the molecules that enzymes can interact with, and the enzyme changes the substrates into new molecules known as products. Almost all cellular metabolic activities require enzyme catalysis in order to proceed at speeds quick enough to maintain life. Enzymes are necessary to catalyze specific steps in metabolic pathways. Enzymology, the study of enzymes, and the pseudoenzyme analysis area acknowledge that some enzymes have lost the capacity to perform biological catalysis during evolution, which is frequently reflected in their amino acid sequences and peculiar "pseudocatalytic" capabilities.

How does an ultrasound produce an image of a fetus in the mother’s uterus?
Elodia [21]
The ultra sound waves coming from the transmitter pass through the body and once they hit a boundary (the baby) they are partially reflected back to the transmitter and the image appears on the screen. The longer the time taken is to reflect, the further away it is, so darker/lighter on the picture.
