How are the reactions of photosynthesis and cellular
respiration interconnected?
Animals rely on photosynthesis in plants, and plants rely on respiration as the
source for
Both reactions require ATP as the energy source, but photosynthesis only
happens in plants.
Every organism carries out both processes at the same time but in different
parts of the organism.
The reactions are opposites of one another, each using the products of the
other as reactants.

- please draw!!! Start with a photon of sunlight and a carbon atom in a molecule of carbon dioxide in the atmosphere: model/diagram their pathway from that starting point to their final destination as a glucose molecule that is used for energy in a cell in the plant root. Following your diagram/model, provide a written explanation for what your diagram/model depicts. Make sure both your model and explanation are clear, concise, and have the appropriate level of detail to clearly demonstrate you understand photosynthesis, cellular respiration, and the movement of mass and energy in plants. PLEASE INCLUDE , how does energy end up in the plant stem?arrow_forwardSelect all that apply about 02 and CO2. O Both are nonpolar molecules. Both can diffuse passively through cell membranes without the help of proteins. O Both are used in cellular respiration. Both are produced in cellular respiration. O Both are small molecules. O Both are hydrophilic molecules. O Oxygen (02) is a cellular respiration input and CO2 is an output. O Co2 is reduced and Oxygen (02) is the product of oxidation. Both are symmetrical molecules. Oxygen (02) gains electrons and is reduced . CO2 is the product of oxidation.arrow_forwardIt is biochemical reactions that enable organisms to harness sunlight to manufacture organic molecules? It is a molecule whose high energy phosphate bonds power many biological processes? This is a disk-like structure that makes up the inner membrane of a chloroplast? These are plant pigments responsible for bright red, yellow and orange colors in many fruits and vegetables?

- Q27. Imagine that NASA’s Spirit Rover discovers a photosynthetic bacterium on Uranus that contains a single pigment. By using an onboard spectrophotometer, the pigment is found to have the absorption spectrum shown below. Which of the following conclusions about this pigment can be deduced from the spectrum shown? The pigment fluoresces green photons. The pigment is blue in colour. The pigment has a single excited state. The pigment reflects high-energy light. A. 1,2 and 3 B. 1 and 3 C. 2 and 4 D. 4 only E. All of 1, 2, 3 and 4 are correct.arrow_forwardIt is biochemical reactions that enable organisms to harness sunlight to manufacture organic molecules?

These are plant pigments responsible for bright red, yellow and orange colors in many fruits and vegetables? These are photosynthetic pigments efficient at absorbing orange, red, yellow, and green light, wavelengths that are not well absorbed by chlorophyll a? TRUE OR FALSE A coupled reaction is a pair of reactions, one exothermic and one endothermic. ATP contains less energy than ADP. In the ATP-ADP cycle, when the phosphate is removed, energy is released. In coupled reaction, an endothermic reaction supplies the energy needed to drive an exothermic reaction. Chlorophyll absorbs green light.arrow_forwardFirst, you should map out all of the biochemical stages and processes in cellular respiration and photosynthesis. This means all of the stages are unpacked in-depth (light-dark Calvin Krebs glycolysis) into stages, their inputs (reactants), outputs (Products), and interdependent molecules (connected molecules). Add more detail to the mind map below about cellular respiration and photosynthesis. (Also added an extra image of what the level of detail should be.)arrow_forward
- In photosynthesis, reaction? which of the following is NOT true about the light-dependent ("light”) Light-excited electrons in chlorophyll provide the energy for ATP production None of the other four answers (All are true of the light-dependent reaction) The light-dependent reaction converts light energy to chemical energy stored in ATP The light-dependent reaction (non-cyclic) captures electrons in NADPH Glucose is synthesized from CO2 and water during the light-dependent reactionarrow_forwardCan someone help me understand this. A student set up an experiment to show the effect of light color on photosynthesis in Elodea plants. She filled two test tubes with distilled water and placed a piece of Elodea in each of the tubes. She added a drop of phenol red, which turns red in a basic solution and yellow in an acidic solution. She blew in each tube before placing the volumeters on the top of the tube. Why did she blow into the tube? to add oxygen to the tube to add carbon dioxide to the tube to add carbohydrates to the tube to add sodium bicarbonate to the tubearrow_forwardGive specific examples Use clear terms Make clear comparisons (how are they both similar a different) Use diagrams/models/graphs t demonstrate your understanding Use the process - identify, explain, connect and, if possible make greater connections/analogies etc. 1) Using either cellular respiration or photosynthesis describe the use of energy and its transformations order to proceed from products to reactants. Explain why the equation for your chosen reaction is misleading for a student learning the process, and also why it is crucial that the transformations happen the way they do and not as a simple combustion reaction: (use of diagrams and/or molecular structures to aid your explanation is highly encouraged) a) Energy Transformations: b) Equations: C6H1206(s) + 602(g) ➡ 6CO2(g) + 6H₂O(g) OR 6CO2(g) + 6H₂O(g) ➡ CH1206(s) + 602(g) c) Combustion reaction: (use of diagrams and/or molecular structures to aid your explanation is highly encouraged)arrow_forward
- For the following questions, choose one to discuss: chloroplast/photosynthesis State at the outset which one you will discuss. A) What role do proton gradients play in the process of photosynthesis proton gradients allow B) Where are proton gradients formed? Within what structures are they seen in chloroplasts How do the structures help them to maintain a gradient? C) Explain where and how the chloroplast or mitochondria uses passive transport and active transport to complete photosynthesis or cellular respiration.arrow_forwardIS THIS A GOOD BREAK DOWN? WHAT ELSE CAN I SHOULD I ADD? Briefly explain the light-dependent reactions of photosynthesis: where does this take place, what are the reactants and what is produced? Light-dependent reactions are used to convert light energy into chemical energy for use by the plants. Through the process of photosynthesis, the energy collected from the sun is broken down, along with water molecules, to produce NADPH and ATP. Light-dependent reactions Goal Convert light energy into chemical energy Location Chloroplasts—thylakoids Input Sunlight, H2O, NADP+, ADP Output NADPH, ATP, O2arrow_forwardThe reactants of photosynthesis are... carbon dioxide + water + light (energy) O oxygen + carbon dioxide O oxygen +glucose O light (energy) + glucose + waterarrow_forward
