DNA, Chromosomes, Nucleus, Cell, Organism
Explanation:
DNA makes up the Chromosomes, which are stored in the nucleus, which is the brain of the cell, and cells make up organisms.
Answer: .OH, O2-, H2O2
Explanation:
Reactive oxygen species (ROS) are chemically reactive and unstable species containing oxygen. ROS are formed when oxygen is partially reduced, thus they are all radicals with very high reactivity, attacking membrane proteins such as ion channels etc
Examples include peroxides (H2O2), superoxide (O2-), hydroxyl radical (.OH)
Answer:
(a) Phosphatases remove the phosphate from GTP on GTP-binding proteins, turning them off
Explanation:
- A molecular switches are molecule that can be reversibly shifted between two or more stable states.
- The molecules may be shifted between the states in response to environmental stimuli, such as changes in pH, light, temperature, an electric current, micro-environment, or in the presence of ions and other ligands.
Answer:
a fuel for cellular respiration and a starting material for making other organic molecules.
Explanation:
Plants have the ability to produce sugars by the process of photosynthesis. Plants can convert the inorganic CO2 from the air into the organic nutrients such as sugars. Plants store sugars so that they can serve as a source of ATP for the cells as and when required. The sugars enter the process of cellular respiration and are oxidized into CO2 and H2O. In addition, the energy of chemical bonds of the sugars is used to form ATP molecules.
Plants also use sugars to synthesize other organic molecules. For example, several intermediates of Kreb's cycle can serve as precursors for the synthesis of amino acids. Amino acids are joined together to form different proteins.
