Biology EOC Review

Front

The sodium potassium pump is an example of ______________________ transport.

Back

Active transport is the movement of ions or molecules across a cell membrane from a region of lower concentration to a region of higher concentration, requiring energy.

Front

When the RNA gets to the ribosomes, which molecule transfers to the mRNA to amino acids?

Back

tRNA (transfer RNA) is responsible for bringing amino acids to the ribosome during protein synthesis.

Front

This image is an example of a _____________ cross.

Back

Dihybrid cross is a genetic cross between individuals that differ in two traits.

Front

The organelle that converts the chemical energy stored in food molecules into compounds that are more convenient for the cell to use:

Back

Mitochondrion is known as the powerhouse of the cell, where cellular respiration occurs.

Front

Endocytosis is an example of ________________ transport.

Back

Active transport, as it requires energy to move substances into the cell.

Front

What is the function of ribosomes in a cell?

Back

Ribosomes are the sites of protein synthesis, where mRNA is translated into amino acid sequences.

Front

Define osmosis.

Back

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

Front

What is the role of chloroplasts in plant cells?

Back

Chloroplasts are organelles that conduct photosynthesis, converting light energy into chemical energy stored in glucose.

Front

What is the difference between prokaryotic and eukaryotic cells?

Back

Prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic cells have a nucleus and organelles.

Front

What is the purpose of the cell membrane?

Back

The cell membrane regulates what enters and exits the cell, providing protection and support.
