The term anabolism refers to those endergonic metabolic pathways involved in biosynthesis, converting simple molecular building blocks into more complex molecules, and fueled by the use of cellular energy.

Autotrophs, like plants, create organic molecules via photosynthesis, whereas heterotrophs, such as humans, obtain energy by consuming organic matter.

A lot of energy is lost to the environment as heat. The story of life is a story of energy flow - its capture, its change of form, its use for work, and its loss as heat. The cells of living things power their activities with the energy-carrying molecule ATP. The cells of most living things make ATP from glucose in the process of cellular respiration. This process occurs in three sta

It describes how energy flows from producers to herbivores (primary consumers) and then to carnivores (secondary and tertiary consumers) in food chains and webs. The text highlights the inefficiency of energy transfer, averaging around 10%, leading to a decrease in energy and biomass at higher trophic levels. This creates pyramids illustrating the balance in ecosystems.

It outlines two metabolic processes: catabolism (breaking down molecules for energy) and anabolism (building larger molecules). Autotrophs, such as plants, synthesize organic molecules through photosynthesis, while heterotrophs, including humans, derive energy from organic matter.

It details how electrons from water create NADPH and generate ATP via photophosphorylation. Chloroplasts house thylakoid membranes with Photosystems I and II for light absorption and electron transfer, facilitating ATP synthesis through chemiosmosis.
