Select one:

a. oxidative phosphorylation

b. the Krebs cycle

c. chemiosmotic coupling

d. glycolysis

Which best describes the extracellular matrix?

Select one:

a. It surrounds cells; it contains proteins, polysaccharides, and minerals; it provides a scaffold for cell attachment; and it transmits chemical messengers to cells.

b. It is found just inside the cell membrane in all tissues, it sends branching collagen fibers between cells to connect them, and it transmits chemical information from the interior of one cell to the interior of adjacent cells.

c. It covers the body's surface, it contains connective and muscle tissue, and it helps generate movement.

d. It is a tissue having more than the four general cell types, it transports proteins and polysaccharides between body compartments, and it is the route by which chemical signals like hormones reach all parts of the body.

Answer 1

1. d) Glycolysis

Glycolysis is carried out by a set of enzymes in the cytosol.

it is the first step of aerobic as well as anerobic respiration. In this step, 1 molecule of glucose of 6 carbon is broken down into 2 molecules of pyruvic acid of 3 carbon.

2. a) it surrounds cell, it contain protiens, polysaccharides, minerals ; it provides a scaffolds for cell attachment ; and it transmit chemical messenger to the cell.

The lymph is known as the extra cellular matrix of cell.
