Diffusion is the movement of molecules from an area of high concentration to an area of low concentration. Diffusion is the movement of molecules from an area of low concentration to an area of high concentration. Diffusion is the movement of molecules across a plasma membrane, regardless of concentration gradient. Diffusion is the movement of molecules from an area of high concentration to an area of low concentration. Which organelle is mainly responsible for synthesizing proteins?

Nucleic acids Phospholipids Fatty acids Triglycerides Phospholipids Which of the following is part of a nucleotide? DNA Amino acid Proteins Sugar Sugar Which is a component of cellular respiration? ATP breakdown Glycolysis Facilitated diffusion Meiosis Glycolysis At what level of protein structure are several amino acid chains joined together? Quaternary Primary Tertiary Secondary Quaternary When solute concentration is lower outside of the cell than inside the cell, water will move in a net direction into the cell.This is called a(n) _________. hypotonic solution What is true about the electron transport chain (ETC)? The largest byproduct of the electron transport chain is carbon dioxide. ATP and water are products of the electron transport chain. The electron transport chain produces the same number of ATP as the Krebs cycle. The electron transport chain takes place in the cytoplasm of the cell. ATP and water are products of the electron transport chain. Which of the following statements is true? For all cells, the nucleus is the control center. Not all cells have cytoplasm. Human beings are made up entirely of cells. The parts that make up cells are themselves living things. Human beings are made up entirely of cells.

It is a double membrane that surrounds the nuclear envelope. It is a pocket in the cell's plasma membrane that houses DNA. It is not found in eukaryotic cells. It houses the cell's DNA. It houses the cell's DNA. Which of the following statements about enzymes is true? Any enzyme in your body is capable of taking part in any type of reaction. An enzyme can act to either join substrates together or break them down. The substrate will be physically different, but not chemically different after being acted upon by an enzyme. Enzymes most often help to slow down reactions in the body. An enzyme can act to either join substrates together or break them down.
