Question

Suppose you plant a seed and observe that a tree of large mass grows from it.The tree achieves a final mass that changes very little for years afterward.which of the following is true about the tree. A Both anabolic and catabolic reactions took place in the seed and tree when it was young and growing but then all reactions stopped when the tree reached a stable mass. B Both anabolic and catabolic reactions took place in the seed and tree when it was young and growing and both continue now even though the tree reached a stable mass. C Only anabolic and catabolic reactions took place in the seed and tree when it was young and growing and only catabolic reactions continue now that the tree reached a stable mass D only catabolic reactions took place in the seed and tree when it was young and growing and only anabolic reactions continue now that the tree has reached a stable mass

Answer 1

The answer should be

B Both anabolic and catabolic reactions took place in the seed and tree when it was young and growing and both continue now even though the tree reached a stable mass.

The trees should be capable to do both anabolic and catabolic reaction when it is seed or when it is already a big tree. Anabolic reaction happens when the plant making bigger molecule from many smaller molecule, such as in photosynthesis. Anabolic reaction could increase the mass of the plants or be used to make food. Catabolism reaction used to extract energy from the food.

Answer 2

Answer:

Suppose you plant a seed and observe that a tree of large mass grows from it. The tree achieves a final mass that changes very little for years afterward. (B) Both anabolic and catabolic reactions took place in the seed and tree when it was young and growing and both continue now even though the tree has reached a stable mass.  

Explanation:

There are two kinds of biochemical or metabolic reactions. These are Anabolic and Catabolic reactions. At any instant, both these reactions are taking place. Anabolic reactions are related with growth. On the contrary, catabolic reactions are related with energy production and liberation of energy.  

 

Further Explanation:  

Catabolic reactions are a sequence of enzyme catalyzed reactions in which bigger molecules are disintegrated into smaller units inside the cells. A portion of the chemical energy released is preserved in the form of ATP (Adenosine Tri Phosphate).

There are three stages in which the energy is liberated:

• First phase involves the breakdown of large biomolecules like lipids, proteins and polysaccharides. In this reaction, only a little amount of energy is liberated.  

• Second phase involves the oxidation of smaller molecules, which gives out chemical energy required to form ATP and also releases heat.  

• In the third phase, oxaloacetate, acetate and alpha-oxoglutarate are converted into carbon dioxide.

In anabolic reactions, the cells take in energy, i.e., anabolic reactions are endergonic reactions. Here smaller molecules bond together to make larger complexes. For example, amino acid units bond together to form bigger protein compounds. Likewise, simple carbohydrate units (disaccharides) combine to create complex carbohydrates (polysaccharides).
