What else can I help you with?
Carbon is used to make sugars in which step of the carbon cycle?
Carbon is used to make sugars in the "carbon fixation" step of the carbon cycle, which occurs during photosynthesis in plants. During this process, carbon dioxide from the atmosphere is converted into organic sugars, which are used for energy and growth by plants.
What is the last step of the Calvin cycle?
The last step of the Calvin cycle is regeneration of RuBP (Ribulose-1,5-bisphosphate) using ATP to continue the cycle. This is necessary to replenish the RuBP molecules that are used in the initial carbon fixation step.
Enzyme used to position nucleotides during DNA replication?
DNA polymerase is the enzyme responsible for positioning nucleotides during DNA replication. DNA polymerase can add nucleotides to the growing DNA strand in the 5' to 3' direction and proofread for errors in base pairing.
Second step in photosynthesis?
The second step in photosynthesis is the light-dependent reactions, which take place in the thylakoid membranes of the chloroplasts. During this step, light energy is absorbed by chlorophyll and water molecules are split, releasing oxygen as a byproduct. This process generates ATP and NADPH, which are used in the Calvin cycle to produce glucose.
What gas is fixed by the plant during Calvin cycle?
carbon dioxide is used in the Calvin cycle.
Describe what occurs during the citric acid cycle?
During the citric acid cycle, also known as the Krebs cycle, acetyl-CoA is oxidized to generate energy in the form of ATP, NADH, and FADH2. This cycle takes place in the mitochondria and involves a series of enzyme-catalyzed reactions that produce carbon dioxide as a byproduct. The citric acid cycle is a key step in cellular respiration, providing electrons that will be used in the electron transport chain to generate more ATP.
How do the reaction help the Calvin cycle?
Light reactions produce NADPH and ATP, which are used during the Calvin cycle.
What step during Krebs cycle do electrons pass down the electron transport chain?
During the Krebs cycle, the electrons are carried by NADH and FADH2 to the electron transport chain, where they pass down a series of protein complexes to generate ATP through oxidative phosphorylation. This occurs after the formation of NADH and FADH2 during the Krebs cycle.
How many ATP produce during kreb cycle?
A total of 38 ATP are produced during the Krebs cycle. Since two ATP are used to start the cycle, there are 36 ATP produced, net.
The instructions in nucleotides are used to make what?
Cells
What is released in step 3 of the Calvin cycle?
In step 3 of the Calvin cycle, the molecule glyceraldehyde-3-phosphate (G3P) is released. It is a three-carbon sugar that can be used to synthesize glucose and other organic compounds essential for plant growth and development.
Which nucleotides are used to build RNA?
ribose sugar and the neucleotides like adenine,guanine,cytocile and uracile
