Front

What is the sodium-potassium pump?

Back

A cellular process that moves three sodium ions out of a cell and two potassium ions into the cell, using energy to transport ions against their concentration gradient.

Front

Why is energy needed for active transport?

Back

Energy is needed because ions are moved against the concentration gradient.

Front

What is a phospholipid?

Back

A molecule that makes up cellular membranes, consisting of a hydrophilic head and two hydrophobic fatty acid tails.

Front

What is the equation for photosynthesis?

Back

6CO2 + 6H2O + sunlight -> 6O2 + C6H12O6.

Front

What are the phases of mitosis in order?

Back

Prophase, Metaphase, Anaphase, Telophase.

Front

What is the significance of genetic material exchange during meiosis?

Back

It increases genetic variation among offspring.

Front

What is active transport?

Back

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

What is the role of ATP in cellular processes?

Back

ATP (adenosine triphosphate) provides energy for various cellular functions, including active transport.

Front

What is the difference between diploid and haploid cells?

Back

Diploid cells contain two complete sets of chromosomes, while haploid cells contain one set.

Front

What is the function of the cell membrane?

Back

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