During photosynthesis, the water molecule is broken into hydrogen and oxygen. The hydrogen atoms are used to form a carrier molecule called NADPH that, later in the photosynthesis process, is broken down to form glucose, a sugar that organisms commonly use for energy.
What is the MBR. The MBR (stands for âMaster boot recordâ) is a boot sector (a region of your hard disk) that holds information about the partitions of your hard drive and acts as a loader for the operating system youâre running. The Master boot record is created when you first install Windows, on the first partition you create. Itâs the first 512 bytes of your hard disk. If the MBR is damaged, you wonât be able to boot into Windows. All Windows versions â Windows XP, Vista, 7 or 8 â use MBR and, if damaged you wonât be able to boot.
