1 ATP SYNTHASE IMAGES

2 This model shows the structure of ATP. The molecule is composed of three parts: a sugar ribose molecule (red and white), a base molecule made up of carbon and nitrogen atoms (grey and purple), and a string of phosphate atoms (orange). These phosphate groups are essential to the function of ATP. When energy is required, ATP is involved in an enzymatic reaction that results in the loss of a phosphate group and a release of energy to form adenosine diphosphate (ADP). During a resting state, when energy is not required, the reverse reaction takes place to reform ATP from ADP. Credit: Anna Tanczos, Wellcome Images Molecular model of ATP

3 An isolated mitochondrion fractured to reveal its internal structure. The internal membranes (cristae), which are visible, are covered with enzyme complexes involved in the conversion of metabolites into energy. This is a colour-enhanced scanning electron micrograph of a freeze-fractured sample. Credit: Dr David Furness, Wellcome Images BIGPICTUREEDUCATION.COM An isolated mitochondrion

4 This colour-enhanced electron micrograph of cells shows the nuclei in green, mitochondria in red, two lysosomes in brown and large amounts of rough endoplasmic reticulum in white. The horizontal field width of the sample is 10.3 micrometres. Credit: University of Edinburgh, Wellcome Images BIGPICTUREEDUCATION.COM Cells with organelles

5 This colour-enhanced image of part of a kidney cell shows many mitochondria in red, a portion of the nucleus in blue and the cytoplasm in green. The cytoplasm is densely packed with the membranes of the endoplasmic reticulum. Credit: Dr David Furness, Wellcome Images BIGPICTUREEDUCATION.COM Mitochondria in the cell cytoplasm

6 This image shows three mitochondria (shown in blue) fractured to reveal their internal structures. The internal membranes (cristae) are visible and are covered with enzyme complexes involved in the conversion of metabolites into energy. The surrounding cytoplasm is shown in gold. This is a colour- enhanced scanning electron micrograph of a freeze-fractured sample. Credit: Dr David Furness, Wellcome Images BIGPICTUREEDUCATION.COM Three mitochondria surrounded by cytoplasm
