The idea that “sugar feeds cancer” is based on the observation that cancer cells consume glucose (a type of sugar) at a much higher rate than normal cells. Here’s how and why this happens: 1. High Glucose Consumption by Cancer Cells Warburg Effect: Cancer cells preferentially use a metabolic process called aerobic glycolysis, even in the presence of oxygen. This process is less efficient than… Read More »How and why does sugar feed cancer cells

ATP (Adenosine Triphosphate) is a molecule that serves as the primary energy carrier in all living organisms. It is often referred to as the “energy currency” of the cell because it provides the energy needed for various biological processes. Structure of ATP: ATP is a nucleotide composed of three main parts: Adenine: A nitrogenous base. Ribose: A five-carbon sugar molecule. Three Phosphate Groups: A chain… Read More »What is ATP?

Parts of the body that lack access to oxygenated blood may not respond to the nervous system because oxygen is essential for the proper functioning of cells, including neurons (nerve cells) and muscle cells. Here’s why this happens: 1. Oxygen’s Role in Cellular Function: Oxygen is necessary for cellular respiration, the process by which cells produce energy (ATP) from glucose. Without oxygen, cells cannot generate… Read More »why do parts of the body that don’t have access to oxygenated blood not respond to the nervous system

The brainstem is a critical part of the brain responsible for controlling many vital and automatic functions necessary for survival. It connects the brain to the spinal cord and acts as a relay center for information between the brain and the body. Here’s what the brainstem controls: 1.
