Photosynthesis

This category is for questions about the chemical process in which autotrophic organisms use sunlight, carbon dioxide and water to make glucose, water and oxygen. This process is vital to life and is of great importance in biology.

Photosynthesis takes how many processes?

The plant absorbs CO2 and oxygen. These molecules are used in the Calvin Cycle, which is also called the light-independent reaction. The products of the Calvin Cycle are then used in the Electron Transport Chain (ETC or Light-Dependent Reaction) to produce ATP.

What kind of energy is produced during photosynthesis?

Solar energy is converted to chemical energy in the form of high energy carbohydrates, usually glucose.

When the CO2 concentration in the cells of a c3 plant is low compared with the o2 concentration an enzyme combines rubp with o2 rather than with CO2 what affect would this have on photosynthesis?

Since photosynthesis requires the carbon from CO2 and its not getting it, the entire process could come to a halt. This would usually occur in hot and dry conditions, where in higher temperatures, the enzyme has a higher affinity for binding to O2 than CO2.

Do photosynthesis and respiration both take in oxygen?

Yes. Both processes require oxygen, but only photosynthesis also produces oxygen.

What are the two molecules that fuel dark reactions?

The two molecules that fuel dark reactions in photosynthesis are ATP (adenosine triphosphate) and NADPH (nicotinamide adenine dinucleotide phosphate). These molecules provide the energy and reducing power needed for the Calvin cycle to convert carbon dioxide into carbohydrates.

What process uses co2 from the atmosphere?

Photosynthesis is the process that uses CO2 from the atmosphere. Plants and other photosynthetic organisms take in carbon dioxide and convert it into oxygen and glucose using sunlight as energy. This process is crucial for maintaining the balance of gases in the atmosphere.

What three things are found in the thylakoid membrane?

  1. Chlorophyll molecules: Responsible for capturing light energy during photosynthesis.
  2. Electron transport chain proteins: Facilitate the transfer of electrons during the light-dependent reactions.
  3. ATP synthase enzyme: Generates ATP by utilizing the proton gradient established across the thylakoid membrane.

Where does glucose come from photosynthesis?

Glucose comes from the dark reaction of photosynthesis. It is formed by the joining of two PGAL molecules.

What are the colored chemical compounds in plants that absorb light?

The colored chemical compounds in plants that absorb light are called pigments. The main pigments responsible for absorbing light in plants are chlorophyll (green), carotenoids (orange and yellow), and anthocyanins (red, purple, and blue). These pigments play a crucial role in photosynthesis, the process by which plants convert light energy into chemical energy.

What is main source of light for photosynthesis?

The main source of light for photosynthesis is the sun. Plants absorb sunlight using a pigment called chlorophyll to convert carbon dioxide and water into glucose and oxygen through the process of photosynthesis.

A green plant can carry out photosynthesis if given nothing more than?

A green plant can carry out photosynthesis with water, carbon dioxide, and sunlight. These are the essential components needed for the plant to produce glucose and oxygen through the process of photosynthesis.

Raw materials produced during light reaction?

The raw materials produced during the light reaction of photosynthesis are ATP (adenosine triphosphate) and NADPH (nicotinamide adenine dinucleotide phosphate), which are used in the subsequent dark reaction (Calvin cycle) to fix carbon dioxide and produce glucose. These molecules store energy generated by capturing light in the form of chemical bonds.

Which gas given off by autotrophic activity made the evolution of aerobes possible?

Oxygen, produced during the process of photosynthesis by autotrophs, was a gas that made it possible for aerobic respiration to evolve. This process allowed for more efficient energy production in organisms, leading to the development and success of aerobic organisms.

What is the function of the proton pumps in the thylakoid membranes?

Proton pumps in the thylakoid membranes of chloroplasts create a proton gradient by pumping H+ ions from the stroma into the thylakoid lumen during photosynthesis. This gradient is utilized by ATP synthase to produce ATP through chemiosmosis.

What does yeast form during fermentation?

Yeast is a fungus. It forms carbon dioxide and alcohol during fermentation.

Do Autotrophs Use Cellular respiration?

Yes, autotrophs use cellular respiration to break down organic molecules and generate energy in the form of ATP. However, autotrophs primarily rely on photosynthesis to produce their own food by converting sunlight into chemical energy.

What are 3 organic compounds in cellular respiration?

The role of organic compounds in cellular respiration is to start cellular respiration. Cellular Respiration is a process that creates ATP. So, in order to create ATP you'll need organic compounds. Organic Compounds are converted into ATP during Cellular Respiration. This is the role of organic compound in cellular respiration.

Can cellular respiration occur without photosynthesis?

Yes, cellular respiration can occur without photosynthesis. Cellular respiration is the process by which cells break down glucose to produce energy, while photosynthesis is the process by which plants convert sunlight into energy. While photosynthesis provides the initial energy source for most living organisms, some organisms (like animals) rely on consuming other organisms for energy through cellular respiration.

Where is the energy from light stored after light reactions?

The energy from light is stored in the form of chemical energy in the molecules ATP and NADPH, which are produced during the light reactions of photosynthesis. These molecules then power the calvin cycle to produce sugars.

What are tools needed in the preparation of raw materials?

Tools needed in the preparation of raw materials typically include knives, cutting boards, mixing bowls, measuring cups and spoons, scales, food processors, blenders, grinders, peelers, and graters. These tools help to cut, chop, blend, measure, grind, and prepare the raw ingredients for cooking or baking.

Where is the location of chlorophyll?

Chlorophyll is located in organelles called chloroplasts, which in turn are located mostly in the leaves of green plants (but there are some in the stems, too).

Does photosynthesis use sunlight to combine the products of cellular respiration?

The simplest way to answer this question is yes. In very general terms photosynthesis is the process of capturing photons for energy that is used for combing the substrates that are the products of aerobic respiration.


Yes, the chemical equation of photosynthesis is:6 CO2 + 6 H2O + Light Energy = C6 H12 O6 + 6 O2Carbon dioxide + Water + Light Energy = Glucose + OxygenRAW MATERIALS = PRODUCTSThe raw materials of photosynthesis are the products of cellular respiration. The rely and use the materials to make the products of photosynthesis with sunlight.

What are the three essential components of a Christian worldview?

The first essential component of a biblical worldview is creation. The second component of a biblical world view, the fall, accounts for these other problems that are encountered ever aspects of life. And the third component of a biblical worldview is redemption.

Where does most of the photosynthesis in the leaf takes place?

Most photosynthesis in a leaf occurs in the mesophyll cells, found in the middle layer of the leaf. Specifically, the chloroplasts within the mesophyll cells are responsible for conducting photosynthesis by capturing light energy and converting it into chemical energy in the form of glucose.
