res no energy and includes diffusion, facilitated diffusion, and osmosis. Molecules move from areas of higher concentration to lower concentration. For example, oxygen diffuses into cells, while carbon dioxide diffuses out. Active Transport
Understanding the stages of cell respiration is crucial, as each step plays a specific role in energy extraction and transfer. 1. Glycolysis Occurs in the cytoplasm. Breaks down one glucose molecule (6 carbons) into two pyruvate molecules (3 carbons each). Produces: 2 ATP molecules (net
NA replication. S phase: DNA replication occurs. G2 phase: Preparation for mitosis; organelles replicate. Mitotic Phase (M phase) Mitosis occurs. Cytokinesis Cytoplasm divides; two daughter cells form. Regulation of the

assessments. A thorough understanding of passive and active mechanisms, their features, and their biological significance not only aids in answering test questions accurately but also deepens overall comprehension
and their ability to grow and divide underpins all biological functions—from tissue repair to organismal development. Cell growth involves the increase in cell size and mass, while cell division is the process by which o
