_____ is a stepwise series of enzyme-mediated reactions that collectively build, remodel, or break down an organic molecules.
Anna11 [10]

Answer:

Metabolic Pathway

Explanation:

This is the interconnected  routes or steps of biochemical reactions that takes place in cells. It is usually facilitated by presence of enzymes. It is initiated with the activity of enzymes on substrates  to form an intermediate products, which  breakdown to  the final products.  The latter can be absorbed directly by the cells or acted upon by another enzymes as substrates . However,the substrates acted upon and final products formed are called the  metabolites.

Based on the energy released or absorbed by the cells  during biochemical reactions, metabolic pathways can be;

Catabolic where  the  breakdown of complex substances into simpler form  involved  the release of large amount of heat. (exergonic). e,g Glycolysis,

and  

when the pathways involved the absorption of large amount of energy (endergonic) during the  synthesis of    new complex products, from  simple substances  the reaction is Anabolic. e,g protein synthesis from amino acids

Chemically both processes are interconnected to complement one another. The heat energy liberated during catabolisim is used by anablolic pathways  for efficiency.This is to  ensure relatively homeostatic status of the body systems with availability of needed metabolites.

Further some metabolic pathways can be both Ana- and Cata-bolic in their pathways, they are said to be Amphibolic. Example of this is in Kreb's Cycle.

The sequence of pathways interconnected pathways of   breaking down and forming of new molecules in cells is called metabolisms.

Fill in the blank with the appropriate term. 1.The___________ is often considered to be the cell's control center. 2.The________
ValentinkaMS [17]
 1.The nucleus is often considered to be the cell's control center.
(because it contains the DNA)

2.The cytoplasm consists of everything inside the plasma membrane of the cell.
(actually it excludes the nucleus)

 3.The plasma membrane forms a boundary between the inside and outside of the cell. - it controls what can enter and what can't!


4.The cytoskeleton is essentially a "skeleton" inside the cell..
it maintains the form of the cell

5.The rough endoplasmic reticulum is covered with
Ribosomes -they make the proteins!


6.Lysosomes use enzymes to break down foreign matter and dead cells.

 7.plant cells cells specifically have a cell wall, a large central vacuole, and chloroplasts.-choloplasts are only found in plants!
