What is Entity Relationship Diagram (ERD)?
Entity Relationship Diagram, also known as ERD, ER Diagram or ER model, is a type of structural diagram for use in database design. An ERD contains different symbols and connectors that visualize two important information: The major entities within the system scope, and the inter-relationships among these entities.

ATP cycle and reaction coupling | Energy (article) | Khan Academy
All this really means is that an appreciable amount of energy is released when one of these bonds is broken in a hydrolysis (water-mediated breakdown) reaction. ATP is hydrolyzed to ADP in the following reaction: ATP + H 2 O ⇋ ADP + P i + energy. Note: P i just stands for an inorganic phosphate group (PO 4 3 −) .

Other functions include the production and secretion of hormones.
27.1 Anatomy and Physiology of the Male Reproductive System
Unique for its role in human reproduction, a gamete is a specialized sex cell carrying 23 chromosomes—one half the number in body cells. At fertilization, the chromosomes in one male gamete, called a sperm (or spermatozoon), combine with the chromosomes in one female gamete, called an oocyte. The function of the male reproductive system (Figure
