Which of the following chemicals is first produced by the Calvin cycle?
The first stable compound produced by the Calvin cycle is 3-phosphoglycerate (3-PGA), formed after carbon fixation of carbon dioxide with ribulose-1,5-bisphosphate (RuBP).
What are three catabolic pathways that together make up the process of cellular respiration?
The three catabolic pathways that make up cellular respiration are glycolysis, the citric acid cycle (Krebs cycle), and oxidative phosphorylation (electron transport chain and chemiosmosis). Glycolysis breaks down glucose into pyruvate, which feeds into the citric acid cycle to produce ATP, NADH, and FADH2. These electron carriers then participate in oxidative phosphorylation to generate most of the ATP produced during cellular respiration.
During cellular respiration what is produced?
Cellular respiration produces ATP from the breakdown of glucose. ATP, NADH, and FADH2 are produced in Glycolysis. NADH and ATP are produced in the Krebs cycle. And 32 ATP and water are produced in the Electron Transport Chain. The first stage of respiration, glycolysis, occurs in the cytoplasm. The later stages occur in the mitochondria.
What happens to pyruvate during alcohol fermentation?
During alcohol fermentation, pyruvate, produced from glycolysis, is converted into ethanol and carbon dioxide. This process occurs in anaerobic conditions, where the pyruvate is first decarboxylated to form acetaldehyde, which is then reduced to ethanol by the enzyme alcohol dehydrogenase. This conversion regenerates NAD+, allowing glycolysis to continue and produce ATP in the absence of oxygen.
What is the first step to breaking down a glucose molecule is?
Breaking down glucose into pyruvate is known as Glycolysis. Glycolysis involves splitting one molecule of the simple 6-carbon sugar glucose into two smaller molecules of the 3-carbon pyruvate. The process is anaerobic and occurs in the cytoplasm of cell.
What is the first stage of cell respiration?
energy is captured form sunlight glycolysis
Describe what happens where during the first step of glycolysis?
during the first step of glycolysis C6 is phosphorylated, turning it into a phosphate ester which is a low energy compound.
In glycolysis ATP molecules are produced by .?

What is the first phase of glycolysis called?
The first phase of glycolysis is called the energy-investment phase, where two molecules of ATP are used to phosphorylate glucose, forming fructose 1,6-bisphosphate.
Which stage of respiration occurs whether or not oxygen is present?
Glycolysis literally means "splitting sugars." Glucose, a six carbon sugar, is split into two molecules of a three carbon sugar. In the process, two molecules of ATP and two "high energy" electron carrying molecules are produced. Glycolysis can occur with or without oxygen. In the presence of oxygen, glycolysis is the first stage of cellular respiration. Without oxygen, glycolysis allows cells to make small amounts of ATP. This process is called fermentation.
What happens to pyruvate during alcohol fermentation?
During alcohol fermentation, pyruvate, produced from glycolysis, is converted into ethanol and carbon dioxide. This process occurs in anaerobic conditions, where the pyruvate is first decarboxylated to form acetaldehyde, which is then reduced to ethanol by the enzyme alcohol dehydrogenase.

The first stable compound produced from CO2 in the light-independent reactions is?
The first stable compound produced from CO2 in the light-independent reactions of photosynthesis is called 3-phosphoglycerate (3-PGA). This compound is formed through the fixation of CO2 by the enzyme Rubisco during the Calvin cycle.
What is the name of the compound glucose is convertes into in the first phase of cellular respiration?
In the first phase, commonly referred to as glycolysis, 1 glucose molecule is converted into 2 pyruvates.
Is rice a c3 plant?
Yes, rice is a C3 plant. This means that it follows the C3 photosynthetic pathway, where the first chemical compound produced during photosynthesis is a three-carbon compound called 3-phosphoglycerate.
