The Calvin cycle involves utilizing carbon dioxide and water to form organic compounds. The reductive TCA cycle, commonly referred to as the reverse Krebs cycle, also produces carbon compounds from carbon dioxide and water.
What is Kreb and Calvin cycle?
The Calvin cycle is part of the light-independent reactions of photosynthesis
. The Calvin cycle uses ATP and NADPH. The Krebs cycle is part of cellular respiration. This cycle makes ATP and NAPH.
What else is the Calvin cycle called?
Calvin cycle is also known as the
C3 cycle
or light-independent or dark reaction of photosynthesis.
What are the intermediates of the Calvin cycle?
The intermediates of the Calvin Cycle include
ADP, NADP+, inorganic phosphate, and 3-phosphoglycerate
.
How would you compare the summary equation of photosynthesis and respiration?
Connecting Cellular Respiration and Photosynthesis
The products of one process are the reactants of the other. Notice that the equation for cellular respiration is the direct opposite of photosynthesis:

What is an important similarity between photosynthesis and cellular respiration?
The similarities are,
they all make energy/food to make energy
. Also, they either create sugar or use sugar. However, cellular respiration has two steps and the first step has glycolysis that occurs in the cytoplasm of cells.
Is TCA aerobic?
The TCA cycle operates during aerobic and anaerobic respiration or fermentation
by running in an oxidative cycle (when respiring oxygen) or in an incomplete, reductive, and branched pathway, respectively.
What is the relationship between photosynthesis and the Calvin cycle?
The carbon atoms used to build carbohydrate molecules comes from carbon dioxide, the gas that animals exhale with each breath.
The Calvin cycle is the term used for the reactions of photosynthesis that use the energy stored by the light-dependent reactions to form glucose and other carbohydrate molecules
.
How are sugars and other molecules synthesized in the Calvin cycle?
The Calvin Cycle
uses the NADPH and ATP from the Light Reactions to “fix” carbon and produce glucose
. Carbon dioxide enters the Calvin Cycle when Rubisco attaches it to a 5-carbon sugar. Most plants fix CO
2
directly with the Calvin Cycle, so they are called C-3 plants.
How does the Calvin cycle differ from the light-dependent reactions?
Light-dependent reactions, which take place in the thylakoid membrane, use light energy to make ATP and NADPH. The Calvin cycle, which takes place in the stroma,
uses energy derived from these compounds to make GA3P from CO2
.
What is Carboxylation in Calvin cycle?
Carboxylation. The first part of the Calvin cycle is the carboxylation step. This is
the point at which inorganic carbon enters the biosphere
. Nearly all organic molecules on the Earth are derived from the products of the carboxylation step of the Calvin cycle.
Is reverse TCA cycle anaerobic?
The chemical reactions that occur are the reverse of what is seen in the TCA cycle.
There are numerous anaerobic organisms that utilize a cyclic reverse TCA cycle
and an example includes organisms classified as Thermoproteus.
How does the TCA cycle function as biosynthetic precursors?
The citric acid cycle is a source of biosynthetic precursors & thus
serves as metabolic integration hub
. an amphibole pathway. must be replenished if any are drawn off for biosynthesis. compounds, which will have significant cataplerotic effects on the cycle.
What are the similarities and differences between photosynthesis and respiration?
| PHOTOSYNTHESIS RESPIRATION | Photosynthesis takes place in the chloroplast and is dependent on light. Respiration takes place in cytoplasm and mitochondria and is not dependent on light. | ENERGY | In photosynthesis, light energy is fixed. In respiration, energy is released. | RAW MATERIALS |

What is the relationship between photosynthesis and respiration quizlet?
What is the relationship between photosynthesis and cellular respiration?
Photosynthesis removes carbon dioxide from the atmosphere, and cellular respiration puts it back
. Photosynthesis releases oxygen into the atmosphere, and cellular respiration uses that oxygen to release energy from food.
What are the similarities between cellular respiration and fermentation?
Similarities:
Both cellular respiration and fermentation are process that break down food and convert the chemical energy stored in the food to ATP molecules
. … That is, cellular respiration takes place in the presence of oxygen, while fermentation takes place in the absence of oxygen.
What are the general features of TCA cycle?
TCA cycle is
actively involved in gluconeogenesis, transamination and
.
Oxaloacetate and α-ketoglutarate
, respectively, serve as precursors for the synthesis of aspartate and glutamate which, in turn, are required for the synthesis of other non-essential amino acids, purines, and pyrimidines.
What are the functions of TCA cycle?
The citric acid cycle, also known as the Krebs cycle or the tricarboxylic acid cycle, is
at the center of cellular metabolism, playing a starring role in both the process of energy production and biosynthesis
. It finishes the sugar-breaking job started in glycolysis and fuels the production of ATP in the process.
Why TCA cycle is Amphibolic?
At each turn of the TCA cycle, oxaloacetate is regenerated and can combine with another acetyl-CoA molecule. The TCA cycle is amphibolic; i.e.,
it serves as a catabolic and an anabolic pathway
. Reactions that utilize intermediates of the cycle as precursors for the biosynthesis of other molecules are as follows.
