Cell Biology Quiz

Cell Biology and Organisation

• Cells have different jobs such as detecting, signalling, digesting, absorbing, fighting infection, and moving.
• Cells perform processes such as making and breaking down molecules, changing membrane voltage, secreting and transporting molecules, and detecting stimuli.
• The cell membrane controls what enters and leaves the cell and contains various proteins and molecules that facilitate different processes.
• The cytoplasm is the material inside the cell membrane and contains water, ions, small molecules, amino acids, and soluble proteins.
• The cytoskeleton helps maintain the cell's shape and consists of filaments and tubules.
• The nucleus contains most of the cell's DNA and controls the cell's activities.
• Ribosomes are the site of protein synthesis, while the endoplasmic reticulum packages and transports proteins and lipids, and the Golgi apparatus modifies, sorts, and packages proteins for secretion or use within the cell.
• Lysosomes use enzymes to break down molecules for recycling, while mitochondria use energy stored in glucose to make ATP.
• Protein functions include antibodies, enzymes, hormonal and structural proteins, storage and transport proteins, and contractile proteins.
• Alternative splicing allows for different proteins to be made from a single gene by chopping out introns and sticking exons together.
• Protein structures include primary, secondary, tertiary, and quaternary structures.
• ATP drives various cellular processes, such as protein synthesis, muscle contraction, molecule transport, and heat production.
