Which process in photosynthesis uses energy from the sun? (1 point) absorbing carbon dioxide splitting water into hydrogen and oxygen combining carbon dioxide and hydrogen releasing oxygen
PLEASE I NEED TO GET THIS DONE TODAY!!!
Can somebody plz help?? I need the answers to the whole test plz ;-;
I need them for today ASAP
plez i am going to fail if i dont get this!
The process in photosynthesis that uses energy from the sun is the "absorbing carbon dioxide" option. Allow me to explain how you can arrive at this answer.
Photosynthesis is the process by which green plants, algae, and some bacteria convert sunlight, carbon dioxide, and water into glucose (a form of sugar) and oxygen. The process occurs in the chloroplasts of plant cells, specifically in the thylakoid membrane.
To determine which process in photosynthesis uses energy from the sun, we should understand the basic steps involved:
1. Light-dependent reactions: These reactions occur in the thylakoid membrane and convert light energy from the sun into chemical energy. In this process, water molecules are split into hydrogen ions (protons), electrons, and oxygen through a process called photolysis.
2. Light-independent reactions (or Calvin cycle): Also known as the dark reactions, these occur in the stroma (the fluid-filled region) of chloroplasts. During this process, carbon dioxide is absorbed from the atmosphere and combined with hydrogen ions and electrons to produce glucose.
Based on this information, we can eliminate the options "splitting water into hydrogen and oxygen" and "releasing oxygen" because these are part of the light-dependent reactions and oxygen is released, not absorbed.
The correct process that uses energy from the sun is "absorbing carbon dioxide" since it occurs in the light-independent reactions, where carbon dioxide is absorbed from the atmosphere and converted into glucose using the chemical energy generated from the light-dependent reactions.
I hope this explanation helps you understand the process involved and how to arrive at the correct answer.
