What heppens when light strikes green plant pigments?
electrons become excited
Photosynthetic bacteria obtain energy by removing electrons from inorganic molecules is true or false?
True. Photosynthetic bacteria obtain energy by removing electrons from inorganic molecules through a process called photosynthesis. This allows them to generate ATP and ultimately produce organic compounds for their growth and metabolism.
Photosynthetic unit where solar energy is absorbed and high energy electrons are generated?
The photosynthetic unit where this occurs is the photosystem. Photosystems I and II are responsible for absorbing solar energy and generating high-energy electrons through the process of photosynthesis. These electrons are then used to power the production of ATP and NADPH, key molecules for further energy conversion in the plant cell.
What are valence electrons for responsible for?
Valence electrons are responsible for chemical boding.
Which molecule is split in photosystem ll?
In photosystem II, water (H₂O) is the molecule that is split during the process of photolysis. This reaction produces oxygen (O₂), protons (H⁺), and electrons, which are essential for the photosynthetic process. The electrons generated from water are then transferred to the electron transport chain, ultimately contributing to the production of ATP and NADPH.
What is an power source?
Ultimately free-electrons derived from - Sunlight, for photosynthetic organisms, and Sulfur for chemoautotrophs.

Describe how high-energy electrons are ultimately responsible for driving the photosynthetic reations?
High-energy electrons generated during the light reactions of photosynthesis are used to create a proton gradient across the thylakoid membrane. This gradient drives the production of ATP, providing the energy needed for the light-independent reactions. Additionally, the high-energy electrons are used to reduce NADP+ to NADPH, which is essential for the synthesis of sugars during photosynthesis.
What are valence electrons for responsible for?
Valence electrons are responsible for chemical boding.
Light excites in photosynthetic pigments?
Light excites two sets of photosynthetic pigments. These are photosystem 1 (PS1) and photosystem 2 (PS2). PS1 is excited by photons at about 700 nanometers, while PS2 is excited at about 680 nanometers.
What is the role of photosystem 2?
The role of photosystem II is to capture sunlight and initiate the process of photosynthesis by using light energy to split water molecules into oxygen, protons, and electrons. This process replenishes electrons in the photosynthetic electron transport chain and ultimately leads to the generation of ATP and NADPH for the Calvin cycle.

Which part of the photosynthetic cycle involves an enzyme taking a molecule of NADP plus and adding two electrons and one proton to it?
The part of the photosynthetic cycle that involves an enzyme adding two electrons and one proton to NADP+ is known as the light-dependent reactions, specifically during the process of photophosphorylation. In this process, electrons are generated from the splitting of water molecules and are transferred through the electron transport chain, ultimately reducing NADP+ to NADPH. This NADPH then plays a crucial role in the subsequent light-independent reactions (Calvin cycle) to synthesize glucose.
Valence electrons are responsible for the makeup of the chemical properties of elements?
Yes, valence electrons are the outermost electrons of an atom and are involved in chemical bonding. The number of valence electrons determines an element's reactivity and ability to form bonds. The arrangement and interactions of valence electrons ultimately determine the chemical properties of an element.
