Riboflavin: The Vitamin That Is Part of the Energy Carrier FADH2

4 min read
Over 90% of the riboflavin in our food is present as the coenzymes flavin adenine dinucleotide (FAD) and flavin mononucleotide (FMN), making riboflavin (vitamin B2) the indispensable precursor for the energy carrier FADH2. This water-soluble vitamin plays a central role in energy production, enabling our bodies to convert nutrients into usable energy.

What are Common Respiratory Substrates?

5 min read
Approximately 30-32 ATP molecules are generated from the breakdown of a single glucose molecule through cellular respiration, highlighting the significance of efficient energy production. These energy-producing molecules are known as common respiratory substrates, which include a variety of organic compounds used by living cells.

Does oxygen come from sugar or nutrients?

4 min read
Over half of the world's oxygen is produced by marine plankton, not rainforests, debunking a common myth. This incredible fact sets the stage for a deeper look into a fundamental biological question: does oxygen come from sugar or nutrients?

How do onions make energy through cellular respiration?

4 min read
According to research published in the Madras Agricultural Journal, the respiration rate of onions decreases with a decrease in storage temperature, which helps to extend their shelf life. This simple observation hints at a complex cellular mechanism: like all living organisms, onions must constantly generate energy to survive and sustain their metabolism, a process distinct from the photosynthesis performed by their green leaves. But how exactly do onions make energy for their bulbs?

How do living things use the energy in food?

4 min read
Over 99% of all living things, including animals, plants, and microorganisms, convert the chemical energy in food into a usable form of energy called ATP through the metabolic process of cellular respiration. Understanding how do living things use the energy in food reveals the fundamental processes that drive life itself.

Does Aerobic Respiration Use Carbohydrates? An In-depth Guide

5 min read
Over 90% of the heat during cellular respiration is produced by carbohydrate metabolism. Aerobic respiration is the process by which cells break down fuel to create energy, and carbohydrates are a primary source of that fuel. Understanding how the body processes carbohydrates for energy is fundamental to grasping cellular metabolism.

How is ATP produced from proteins? A complete guide to metabolic pathways

5 min read
Approximately 10-15% of the body's total energy production can come from amino acid catabolism, making it a critical backup fuel source during fasting or high-protein intake. Understanding how is ATP produced from proteins reveals the intricate metabolic flexibility of the human body, turning structural components into usable energy.

The Cellular Process of Food Utilisation Explained

2 min read
The human body requires a constant supply of energy to fuel all its life-sustaining processes, from muscle contraction to DNA synthesis. The critical biochemical process that extracts this energy from the food we eat is called cellular respiration, which explains the process of utilisation of food by the cells.

Why is eating food chemical energy?

4 min read
Over 90% of a cell's energy comes from a process that converts the food we eat into usable power. When you eat, you are essentially ingesting packets of chemical energy, with the body acting as a sophisticated machine designed to extract and utilize this stored power.
