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.
ï· BIOS systems boot from a MBR type disk, EFI systems are designed to boot from either MBR or ESP type partition. ï· To boot from a GPT type disk, the computer must support EFI. ï· GPT type disk use a primary and backup partition tables for redundancy. MBR does not have a redundant feature. ï· Master Boot Record (MBR) is the original disk initialization system that maintains a master boot record to locate.
