Is the carrier molecule involved in photosynthesis?
In the light-dependent reactions, energy from sunlight is absorbed by chlorophyll and converted into stored chemical energy, in the form of the electron carrier molecule NADPH (nicotinamide adenine dinucleotide phosphate) and the energy currency molecule ATP (adenosine triphosphate).
What is the carrier molecule for photosynthesis cellular respiration?
Glucose
Glucose (C6H12O6,) is a nearly universal fuel delivered to cells, and the primary product of photosynthesis. ATP molecules store smaller amounts of energy and are used within cells to do work.
What is the final electron carrier molecule in photosynthesis?
Both copper- and iron-containing proteins function in electron transport between water and the final electron-acceptor molecule of the light stage of photosynthesis, an iron-containing protein called ferredoxin.
What is a carrier molecule?
1 A molecule that plays a role in transporting electrons through the electron transport chain. Carrier molecules are usually proteins bound to a nonprotein group; they can undergo oxidation and reduction relatively easily, thus allowing electrons to flow through the system.
What is a carrier molecule quizlet?
Terms in this set (6) what are electron carrier molecules? molecules that are used to carry electrons and hydrogen ions to the last step of cellular respiration.
What are energy carrier molecules?
Adenosine triphosphate, or ATP, is the primary energy carrier molecule within cells. It is produced from the breakdown of glucose during cellular respiration, and can be split into ADP and inorganic phosphate in a process that releases energy to fuel cellular processes.
How is energy released from carrier molecules?
Through a series if small steps, free energy is released from sugar and stored in carrier molecules in the cell (ATP and NADH, not shown). Rather than burning all their energy in one large reaction, cells release the energy stored in their food molecules through a series of oxidation reactions.
What is the function of an electron carrier?
Electron carriers, sometimes called electron shuttles, are small organic molecules that readily cycle between oxidized and reduced forms and are used to transport electrons during metabolic reactions.
What are electron carrier molecules?
What do carrier molecules transport?
A carrier molecule is typically involved in the transport of other biological compounds such as proteins, DNA or RNA, electrons, or protons including ions. For example, carrier proteins can transport other molecules such as ions, sugar, fat, or peptides through the cell membrane.
