Biology Exam 2020

Front

What are the products of photosynthesis?

Back

Oxygen and glucose are the products of photosynthesis, which occurs in plants, algae, and some bacteria, converting light energy into chemical energy.

Front

What type of materials are expelled from the cell during exocytosis?

Back

Large molecules such as hormones are expelled from the cell during exocytosis, a process that involves the fusion of vesicles with the plasma membrane.

Front

Which movement of materials through a membrane, against the concentration gradient requires energy?

Back

Active transport is the movement of materials through a membrane against the concentration gradient, requiring energy in the form of ATP.

Front

Which organelle is made up of two parts and transports synthesized proteins?

Back

The endoplasmic reticulum is the organelle that is made up of two parts (rough and smooth) and is responsible for transporting synthesized proteins.

Front

What are the reactants of cellular respiration?

Back

The reactants of cellular respiration are oxygen and glucose, which are used to produce energy in the form of ATP.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy, producing glucose and oxygen from carbon dioxide and water.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

What is the role of ribosomes in a cell?

Back

Ribosomes are the cellular structures responsible for protein synthesis, translating messenger RNA into polypeptide chains.

Front

What is osmosis?

Back

Osmosis is the passive movement of water molecules across a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What is diffusion?

Back

Diffusion is the passive movement of molecules from an area of higher concentration to an area of lower concentration until equilibrium is reached.
