An enzyme is a protein molecule in cells which works as a biological catalyst. *brainliest pls*
Enzymes are made of strings of amino acids chemically bonded to one another. These bonds give each enzyme a unique structure, which determines its function. They mostly break down carbohydrates and fats. Once a protein source reaches your stomach, hydrochloric acid and enzymes called proteases break it down into smaller chains of amino acids. Amino acids are joined together by peptides, which are broken by proteases.
The endocrine system is composed of glands that release insulin, a natural agent that breaks down sugars and glucose in the blood.
Answer:
Flowers and fruits
Explanation:
The plants which possess vascular tissues are known as the vascular plants like the pteridophytes, gymnosperms and angiosperms and the plants which do not contain the vascular tissues are known as nonvascular plants like the thallophytes and the bryophytes.
In the given features all the provided options are present in the vascular plants and absent in the non-vascular plants but flowers and fruits are the option which is found in some vascular plants especially in the plants of the angiosperm families and are absent in non-vascular plants also.
Thus, Flowers and fruits are the correct answer.
