Front

Monomers of carbohydrates are called:

Back

Monosaccharides are the simplest form of carbohydrates, consisting of single sugar molecules like glucose and fructose.

Front

What is the optimum pH of the enzyme based on the graph?

Back

The optimum pH of the enzyme is 6.6, where the enzyme activity is highest.

Front

What type of cell is characterized by the absence of a nucleus?

Back

Prokaryotic cells are unicellular organisms that lack a membrane-bound nucleus.

Front

What structure regulates the movement of substances in and out of the cell?

Back

The cell membrane, composed of phospholipids, controls the entry and exit of substances.

Front

What is the optimal temperature for enzyme activity based on the graph?

Back

The optimal temperature for the enzyme is 30°C, where the enzyme activity peaks.

Front

Define 'enzyme'.

Back

An enzyme is a biological catalyst that speeds up chemical reactions in living organisms.

Front

What are the two main types of cells?

Back

The two main types of cells are prokaryotic and eukaryotic cells.

Front

What is the function of the nucleus in a cell?

Back

The nucleus houses the cell's genetic material (DNA) and controls cellular activities.

Front

What is a phospholipid?

Back

A phospholipid is a type of lipid molecule that forms the bilayer of cell membranes, consisting of a hydrophilic head and hydrophobic tails.

Front

What is the role of ribosomes in a cell?

Back

Ribosomes are the cellular structures responsible for protein synthesis.
