A Neat target of p53 - Nature.com


Nature.com
The tumour suppressor p53 is activated by various types of cellular stress, including DNA damage and oncogenic signalling. Activated p53 induces the transcription of a plethora of genes, leading to cell cycle arrest or apoptosis, and to tumour suppression.

Cellular Respiration - Bozemanscience

Bozeman, Montana - United States

Paul Andersen covers the processes of aerobic and anaerobic cellular respiration. He starts with a brief description of the two processes. He then describes the important parts of the mitochondria. He explains how energy is transferred to ATP through the processes of glycolysis, the Kreb cycle and the Electron Transport Chain.

Understanding Cellular Respiration
United States

Process by which food is broken down by the body's cells to produce energy in the form of ATP molecules.

United States

Life is possible only if molecules and cells remain organized. Organization requires energy, as governed by the laws of thermodynamics. Just about anything a living organism does requires energy. We most often think of energy as food or calories. Cells, however, think of energy as ATP. Cellular respiration is the process of taking the food we eat (like sugar) and converting it into an energy that can be used by cells - ATP.

Cell Respiration
United States

Cellular respiration is the process by which the chemical energy of "food" molecules is released and partially captured in the form of ATP. Carbohydrates, fats, and proteins can all be used as fuels in cellular respiration, but glucose is most commonly used as an example to examine the reactions and pathways involved.
