Which of the following structures is responsible for the production of ribosomes?

The nucleolus is like a factory inside the cell?s nucleus that builds ribosomes, which are tiny machines that make proteins. These ribosomes then leave the nucleus and do their job in the cytoplasm.

In which phase of the cell cycle does DNA replication occur?

The S phase is like photocopying all the pages of a book before splitting the book into two. This is where the cell makes an exact copy of its DNA so that when it divides, each new cell will have a complete set of instructions.

What is the role of insulin in the human body?

Insulin is like a key that opens the doors on cells, letting sugar (glucose) in. When blood sugar levels rise after you eat, insulin helps bring them back down by allowing the sugar to enter cells where it can be used for energy.

What type of cell division results in the production of gametes?

Meiosis is like cutting the number of chromosomes in half to prepare for the next generation. It makes sure that each sperm or egg cell has half the usual number of chromosomes so that when they combine during fertilization, the resulting offspring have the right amount.

Which of the following best describes the function of tRNA during protein synthesis?

tRNA is like a delivery truck that brings the right amino acids to the ribosome, which is where proteins are made. Each tRNA matches with a specific mRNA codon to add the correct building block to the growing protein.

What is the primary function of hemoglobin in the body?

Hemoglobin is like a bus that carries oxygen from the lungs to the rest of the body. Each hemoglobin molecule in red blood cells binds oxygen and delivers it to tissues that need it.

Which process describes the movement of water across a semi-permeable membrane?

Osmosis is like water moving from a crowded room to an empty one, but it can only go through a special door (the semi-permeable membrane). The water moves to balance out the concentration on both sides.

In the human body, which enzyme is primarily responsible for the digestion of proteins?

Pepsin is like a pair of scissors in the stomach that cuts long protein chains into smaller pieces so the body can absorb them. It works in the acidic environment of the stomach to break down proteins.

Which of the following is responsible for the majority of ATP production in a eukaryotic cell?

Mitochondria are like the power plants of the cell. They take in nutrients and oxygen and use them to produce energy (in the form of ATP) that the cell can use to function.
