You are watching: Which statement is true regarding the light reactions?
The first action to tackling this problem is to recall what the light independent reactions actually are so we have the right to get rid of answer choices. Remember, that light independent reactivity does NOT call for light and is occasionally described as the Calvin cycle or dark reactions. This process takes place in the stroma of the chloroplast. This process is likewise known as carbon fixation, wbelow CO2 is provided with other molecules (ATP and NADPH) to create glucose. The cycle must repeat itself 6 times prior to a molecule of glucose can be made. All of the indevelopment I presented to you is at the "memorization" level of learning- I typically tell my students to make flashcards to help them through this form of studying.
Which is not true about the light-independent reactions?
These reactions transform carbon dioxide right into glucose molecules.- This statement is true. Throughout the light-independent reactions, ATP and NADPH (from light dependent reaction) and also 3 molecules of CO2 are provided to produce glucose. This form of answer is based being able to respeak to particular information- use flashcards to assist you memorize this type of information.
These reactions call for ATP and also NADPH made in the light-dependent reactions. This statement is true. Throughout the light-independent reactions, ATP and also NADPH (from light dependent reaction) and 3 molecules of CO2 are used to create glucose. This kind of answer is based being able to recontact particular information- use flashcards to aid you memorize this indevelopment.
These reactions take location in the chloroplasts. This alternative was a small tricky, if you understand that this process takes place in the stroma you might have actually foracquired that the stroma remained in the chloroplast.
These reactions happen utilizing three O2 molecules at a time. This alternative was wrong- it provides 3 CO2 molecules at a time. This alternative was kind of the opposite of the correct answer. I favor to think of oxygen and also carbon dioxide as opposites.

As a former teacher, I can tell you that many concerns about photosynthesis and also cellular respiration are going to be memorization kinds of concerns quite than principle questions. It"s crucial that you know the steps, what happens, what is provided, and what is created each process- use flashcards!
