24 - 25 Biology Fall Final Review

Front

What is the primary function of mitochondria in cells?

Back

Mitochondria create ATP (adenosine triphosphate), which is the energy currency of the cell.

Front

What is the complementary DNA strand for the sequence AGG-TAA-CCA?

Back

The complementary DNA strand is TCC-ATT-GGT.

Front

What is a deletion mutation?

Back

A deletion mutation is a mutation in which a section of DNA is removed.

Front

Which type of transport requires ATP energy?

Back

Active Transport requires ATP energy.

Front

Which type of cell in the human body would need the most mitochondria?

Back

Muscle cells need the most mitochondria due to their high energy demands.

Front

What is the role of ATP in cellular processes?

Back

ATP serves as the primary energy carrier in cells, providing energy for various biochemical reactions.

Front

Define facilitated diffusion.

Back

Facilitated diffusion is a process of passive transport that allows substances to cross membranes with the assistance of special proteins.

Front

What is the difference between active transport and passive transport?

Back

Active transport requires energy (ATP) to move substances against their concentration gradient, while passive transport does not require energy and moves substances along their concentration gradient.

Front

What is the structure of DNA?

Back

DNA is a double helix composed of nucleotides, which include a sugar, a phosphate group, and a nitrogenous base.

Front

What are the four nitrogenous bases in DNA?

Back

The four nitrogenous bases in DNA are adenine (A), thymine (T), cytosine (C), and guanine (G).
