12.5: ATP Production

Figure 12.5.1 12.5. 1: Phase 1 (preparatory phase) of Glycolysis. When glucose enters a cell, it is immediately phosphorylated to form glucose 6-phosphate, in the first reaction of phase I. The phosphate donor in this reaction is ATP, and the enzyme—which requires magnesium ions for its activity—is hexokinase.

How Cells Obtain Energy from Food

Through the production of ATP, the energy derived from the breakdown of sugars and fats is redistributed as packets of chemical energy in a form convenient for use elsewhere in the cell. Roughly 10 9 molecules of ATP are in solution in a typical cell at any instant, and in many cells, all this ATP is turned over (that is, used up and replaced) every 1–2 minutes.

The degree of coupling of energy derived from oxidation to the generation of ATP varies across different tissues, individuals, environment and species, and over the lifetime of an individual [49,53–56], leading to variation in the efficiency of ATP production.

Introduction to cellular respiration and redox

The basic answer is: to get energy out of that glucose molecule! Here is the glucose breakdown reaction we saw at the beginning of the article: C 6 H 12 O 6 + 6 O 2 → 6 CO 2 + 6 H 2 O Δ G = − 686 kcal/mol. Which we can rewrite a bit more clearly as: C 6 H 12 O 6 + 6 O 2 → 6 CO 2 + 6 H 2 O + energy!

Energy storage

Energy storage is the capture of energy produced at one time for use at a later time [1] to reduce imbalances between energy demand and energy production. A device that stores energy is generally called an accumulator or battery. Energy comes in multiple forms including radiation, chemical, gravitational potential, electrical potential ...

6.3: ATP in Living Systems

When ATP is broken down, usually by the removal of its terminal phosphate group, energy is released. The energy is used to do work by the cell, usually by the released phosphate binding to another molecule, activating it. For example, in the mechanical work of muscle contraction, ATP supplies the energy to move the contractile muscle proteins.

Energy flow & primary productivity (article) | Khan Academy

Primary producers (usually plants and other photosynthesizers) are the gateway for energy to enter food webs. Productivity is the rate at which energy is added to the bodies of a group of organisms (such as primary producers) in the form of biomass. Gross productivity is the overall rate of energy capture. Net productivity is lower, adjusted ...

ATP synthesis and storage

Hence, ATP cannot be stored easily within cells, and the storage of carbon sources for ATP production (such as triglycerides or glycogen) is the best choice for energy maintenance. Surprisingly, in 1974, Dowdall [ 79 ] and co-workers found a considerable amount of ATP (together with acetylcholine) in cholinergic vesicles from the electric organ …

Storage efficiency
