Key Definitions and Concepts

• Cell: The basic structural and functional unit of all living organisms.

• Metabolism: The sum of all chemical reactions that occur within a living organism to maintain life.

• Gene: A segment of DNA that encodes information for the synthesis of a specific protein.

• Evolution: The process by which populations of organisms change over generations through variations and natural selection.

• Osmosis: The diffusion of water across a selectively permeable membrane.

• Enzyme: A biological catalyst that speeds up chemical reactions in cells.

• Photosynthesis: The process by which green plants and some other organisms use sunlight to synthesize food from carbon dioxide and water.

• Cellular Respiration: The process by which cells break down glucose and other molecules to produce ATP, the cell’s energy currency.

Example: Mendelian Genetics

• Law of Segregation: Each individual has two alleles for each gene, which segregate during gamete formation so that each gamete carries only one allele.

• Law of Independent Assortment: Genes for different traits can segregate independently during the formation of gametes.

• Punnett Square: A diagram used to predict the outcome of a particular genetic cross.

• Example: Crossing two heterozygous pea plants (Yy x Yy) for seed color yields a 3:1 ratio of yellow to green seeds.

Example: Photosynthesis Equation

The overall chemical equation for photosynthesis is:

$6CO_2 + 6H_2O + light\ energy \rightarrow C_6H_{12}O_6 + 6O_2$

Example: Cellular Respiration Equation

The overall chemical equation for aerobic cellular respiration is:

$C_6H_{12}O_6 + 6O_2 \rightarrow 6CO_2 + 6H_2O + ATP$
