B) a hollow ball of cells
The correct answer should be <span>biosphere, atmosphere, and geosphere
Soil belongs to geosphere just like the nutrients, the carbon dioxide belongs to the atmosphere, that is the air, and the plant is a living being which is why it belongs to the biosphere.</span>
Answer:
C. Electrons are released into the electron transport system.
Explanation:
Photosynthesis has both light dependent processes and light-independent processes. In the light-dependent reactions, photosystem II is the first protein complex. Photosystem II is present in the thylakoid membrane of plants.
<em>When the photons or light energy hits photosystem II, the free electron excites and released into the electron transport system (series of proteins). </em>The electron then passes through electron transport system and the energy from the electron fuels the hydrogen ions to move against their concentration gradient. Once the energy is utilized, the electron is accepted by photosystem I.
Hence, the correct option is C.
enzymes are proteins that speeds up the rate of chemical reaction in a living organism . An enzyme acts as catalyst for specific chemical reaction, converting a specific sets of reactants called substrates into specific products with out enzymes life would not be exist
Explanation:
Enzymes are identified to catalyze more than 5,000 biochemical reaction types. Most enzymes are proteins, although a few are catalytic RNA molecules. Enzymes' specificity appears in their unusual three-dimensional structures. Like all enzymes, enzymes improve the reaction rate by decreasing its activation potential.
A. It generally releases more heat than nuclear fission.
