What evidence supports a Conservation Law 6 co2?
Answer: The evidence that supports the conservation law is that Carbon dioxide becomes glucose and oxygen during photosynthesis. The law of conservation of mass states that in a chemical reaction, mass is neither created nor destroyed.
How is mass and energy conserved during photosynthesis?
The AMOUNT of oxygen and carbon atoms released by photosynthesis are EXACTLY EQUAL to the atoms of these material contained in carbon-dioxide converted. In this way photosynthesis has conserved the mass or material, and in this way followed the law of conservation of mass.
Which description properly describes the plant structures?
The correct answer is that “xylem transports water, stomata take in carbon dioxide, and chlorophyll absorbs sunlight.” The xylem is a vascular structure in plants that transport water, the phloem is another vascular structure in plants that transport nutrients.
Why do you think plants have different structures?
The reason that plant cells have the extra structures is that plants harness and store their energy in a different way than animals do. First of all, plants get their energy from the sun, whereas the start of the animal food chain is a plant.
What are plant structures?
The main structures or ‘organs’ found in plants are the leaves, stems and roots. They are made up from groups of specialised tissues that have structures suited to the jobs they perform. The table below summarises the main features of these structures and their functions.
Which description properly describes a step involved in cellular respiration?
Which description properly describes a step involved in cellular respiration? – Glucose is created, then the energy gained is transferred to the energy molecule. – Carbon dioxide and water are released after the energy molecule is charged.
What are the 7 steps of cellular respiration?
Overview of the steps of cellular respiration. Glycolysis. Six-carbon glucose is converted into two pyruvates (three carbons each). ATP and NADH are made….
- Glycolysis.
- Pyruvate oxidation.
- Citric acid cycle.
- Oxidative phosphorylation.
What will be made by one glucose molecule in the presence of oxygen?
In aerobic conditions, the process converts one molecule of glucose into two molecules of pyruvate (pyruvic acid), generating energy in the form of two net molecules of ATP.
How does the presence of oxygen affect the chemical pathways used to extract energy from glucose?
If oxygen is available, glycolysis is followed by two processes in the mitochondria — the Krebs cycle and oxidative phosphorylation, respectively — that further increase ATP yield. produces only a small amount of energy. the breakdown of glucose by enzymes, releasing energy and pyruvic acid.
WHY CAN T cells directly use the energy from glucose?
(7.1) Why don’t cells just link the oxidation of glucose directly to cellular functions that require energy? Linking the oxidation of glucose to all of the functions that require energy would be inefficient: the cell might lose energy produced by the oxidizing glucose if all of the energy wasn’t needed immediately.
Why is respiration a better method than fermentation for extracting energy from glucose?
Why is respiration a better method than fermentation for extracting energy from glucose? – Respiration uses up the NADH produced in glycolysis, producing more ATP. – Fermentation uses up the NADH produced in glycolysis without producing any more ATP. – Fermentation produces a toxic by-product that must be broken down.
How are respiration and burning similar and different?
Explanation: Similarity: Both the process of respiration and burning utilize oxidation to release energy. Difference: Respiration is a biological process and under biological control and takes place at room temperature. Burning is a chemical and uncontrolled process and takes place at high temperature .
What is the difference between combustion and burning?
1 Answer. The basic difference is that combustion is heating and no flames are produced whereas in burning most of the energy is converted to light energy and this results in less heat energy as compared to combustion.
What are the similarities between this equation for burning glucose and the equation for cellular respiration of glucose when oxygen is available?
2. The following is the chemical equation for when combustion of glucose. What are the similarities an differences between the equation for burning glucose and the equation for cellular respiration in the presence of oxygen? The equations are nearly exactly the same except the form of energy.
Which bonds of glucose are broken down by oxidation during respiration?
Respiration refers to the process of breaking down complex organic molecules (i.e. respiratory substrates) into simpler substances in the presence of oxygen. Precisely, the carbon-carbon (C-C) bonds are broken during this biochemical reaction.
Why do eukaryotes have 36 ATP?
As a result, between 1 and 2 ATP are generated from these NADH. In eukaryotic cells, the theoretical maximum yield of ATP generated per glucose is 36 to 38, depending on how the 2 NADH generated in the cytoplasm during glycolysis enter the mitochondria and whether the resulting yield is 2 or 3 ATP per NADH.
What is the net gain of ATP for glycolysis?
two
