D. integrins. Explanation: The extracellular matrix comprises a complex framework of proteins and carbohydrates found in the areas outside cells. Collagen proteins, modified with carbohydrates, form collagen fibers that intertwine with proteoglycan complexes consisting of polysaccharides and proteins. This structure is vital for maintaining mechanical strength and structural support for tissues. Integrins, located within the cell membranes, are essential connections between fibers in the extracellular matrix and neighboring cells. They also enable cell communication by detecting both mechanical and chemical signals from the extracellular matrix and triggering intracellular signaling pathways.

* Required 1. The stems and fruits of pineapple plants contain a group of protein-digesting enzymes collectively called bromelai
vlada-n [2515]

Answer:

Bromelain refers to a collection of proteases containing sulfhydryl groups. Each protease consists of amino acids, which are the fundamental components of proteins.

Explanation:

Bromelain:

It is not classified as a singular enzyme. Instead, it comprises a combination of proteolytic enzymes along with phosphatases, glucosidases, peroxidases, cellulases, and glycoproteins. Initially, bromelain was identified as an enzymatic mix derived from pineapple plants (Ananas comosus), but it is now recognized as any protease sourced from the Bromeliaceae family.

Proteins are large molecules made up of amino acid subunits or monomers. These amino acids, linked by peptide bonds, create the intricate structure of enzymes.
