Answer: tyrosine and phenylalanine
Explanation:
Chymotrypsin is a mammalian digestive enzyme that catalyzes the hydrolysis of proteins in the small intestine. it is highly selective in its action as it hydrolyzes only those peptide bonds on the carboxyl side of AROMATIC AMINO ACIDS such as tyrosine, phenylanine, tryptothan.
Thus, of all listed tyrosine and phenylalanine are the amino acids.
When the starfish were removed from the area as part of an experiment, the mussel population swelled and crowded out other species. The biodiversity of the ecosystem was drastically reduced. Payne's study showed that identifying and protecting keystone species can help preserve the population of many other species.
Answer:
A. Earth is to the Moon.
Explanation:
Planets orbit around the Sun, similarly, the Moon orbits around the planet Earth. So, answer choice A is the correct option.
Answer:
Pulse chase experiment was performed to find the secretory pathway of proteins inside the cell. The protein sorting and pathway of protein can easily be studied by the pulse chase experiment.
The molecule is labelled with radioactive component and its pathway is observed during the pulse chase experiment. The molecule reside 5 minutes in rough ER. After this 40 minutes in glogi apparatus. From the golgi apparatus the molecules moves towards the endosomes and resides for 70 minutes. The molecules then transferred to lysosomes in 140 minutes. This chasing explains the pathway of the molecule.
The pathway can be drawn is ER→golgi→endosome→lysosome.
