Biology Semester 1 MEGA Review

Front

What is diffusion?

Back

Diffusion is the process by which particles move from areas of high concentration to areas of low concentration.

Front

What type of biomolecule is helicase?

Back

Helicase is a protein that helps to unwind DNA strands during replication.

Front

Define cohesion in the context of water.

Back

Cohesion is the attraction between water molecules that causes them to stick together, leading to the formation of drops.

Front

What role does polymerase play in DNA replication?

Back

Polymerase is the enzyme that bonds together the new side of the DNA during replication.

Front

What are the two products of the light reactions needed for the Calvin cycle?

Back

NADPH and ATP are the two products of the light reactions that are required for the Calvin cycle.

Front

What is the function of ligase in DNA replication?

Back

Ligase is the enzyme that joins together Okazaki fragments on the lagging strand during DNA replication.

Front

Explain the process of endocytosis.

Back

Endocytosis is the process by which cells engulf substances from their external environment, bringing them into the cell.

Front

What is the difference between adhesion and cohesion?

Back

Adhesion is the attraction between different substances, while cohesion is the attraction between similar substances, such as water molecules.

Front

What is the primary function of photosynthesis?

Back

Photosynthesis is the process by which plants convert light energy into chemical energy in the form of glucose.

Front

Define the term 'enzyme'.

Back

An enzyme is a protein that acts as a catalyst to speed up chemical reactions in biological processes.
