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.

The energy acquired in the light-dependent reaction is used in the light-independent reaction to build glucose molecule show is this energy transferred from light-dependent to light-independent react?

Glencoe Science; BIOLOGY

Light energy is absorbed and then converted into chemical energy in the form of

ATP and NADPH. The ATP and NADPH that were formed in phase one are used

to make glucose.

How does photosynthesis adapt to a tomato plant?

A tomato plant utilizes photosynthesis by absorbing sunlight through its leaves to convert carbon dioxide and water into glucose for energy. The plant's chlorophyll captures sunlight energy during the light-dependent reactions, which fuels the production of ATP and NADPH. These energy-rich molecules are then used in the light-independent Calvin cycle to convert carbon dioxide into glucose. Ultimately, this process helps the tomato plant to grow and produce fruit.

Carbon fixation and photolysis usually take place in a plants?

know im trying to find that answer to i hate biology espically the teacher and i cant find this answer snywhere and i dont want to read to find the answer i thought the internet is supposed to help you with your hw. Its messed up i have been on 6 different sites and none of them told me the anser. Sorry this didnt help you any but maybe we will have to use the book to figure ths out.SORRY AGAIN

Is PGAL formed in the Calvin cycle a six carbon compound?

Yes, PGAL (phosphoglyceraldehyde) is a three-carbon compound produced during the Calvin cycle through the fixation of CO2 by RuBisCO. It is not a six-carbon compound.

To produce one glucose the calvin cycle needs to be run through?

The Calvin cycle needs to be run through six times to produce one molecule of glucose. This is because each turn of the Calvin cycle fixes one molecule of carbon dioxide, and glucose has six carbons in its structure.

In cells what is the source of energy for an endergonic reaction?

In cells, the source of energy for an endergonic reaction is usually adenosine triphosphate (ATP). ATP provides the necessary energy molecule for the endergonic reactions to occur by transferring phosphate groups to molecules in order to drive the reaction forward.

What are two processes that work together to cycle oxygen through an ecosystem?

Photosynthesis and respiration are two processes that work together to cycle oxygen through an ecosystem. During photosynthesis, plants and other organisms produce oxygen, while during respiration, organisms use oxygen for cellular respiration, releasing carbon dioxide back into the atmosphere.

How does starch's location in leaves prove photosynthesis?

To clarify: We boiled alcohol with a leaf and tested for starch with iodine (present in the veins), We also covered a leaf with tin foil and came back the next day. The leaf was more green in the veins and more discolored farther away from the veins. This lab was suppose to show us glucose is made by the leaf, but all it proves is that starch is in the veins, right?

Does yeast have chlorophyll?

No, yeast does not have chlorophyll because it has no need for it. It is a type of fungus, so it is a decomposer. Producers would have chlorophyll because they need to make their own "food."

Why a toxin that inhibits an enzyme of the Calvin cycle will also inhibit the light reactions?

Inhibiting an enzyme of the Calvin cycle disrupts the production of organic molecules needed for the light reactions. This disrupts the flow of electrons and protons in the thylakoid membrane, ultimately affecting the synthesis of ATP and NADPH. Consequently, the overall process of photosynthesis is impaired, leading to inhibition of the light reactions.

Where is ATP needed in the Calvin cycle?

ATP is needed in the Calvin cycle to power the phosphorylation of molecules, such as the conversion of ribulose-1,5-bisphosphate (RuBP) to 3-phosphoglycerate. This process requires energy from ATP to facilitate the necessary chemical reactions for carbon fixation.

What is reduced by electrons in light reactions?

In light reactions of photosynthesis, electrons are reduced by the pigment molecule chlorophyll to produce NADPH and ATP. These reduced molecules carry energy and electrons to the Calvin cycle for the synthesis of carbohydrates.

Why does carotenes move more rapidly with the solvent then the xanthophylls?

Carotenes are less polar than xanthophylls, so they have a greater affinity for the nonpolar solvent used in chromatography. This difference in polarity causes the carotenes to move more rapidly through the chromatography column compared to xanthophylls.

What is the entire process by which a body obtains and uses oxygen and gets rid of carbon dioxide and water called?

The process by which animals take in food and oxygen and give off carbon dioxide is called cellular respiration. Plants, on the ore hand, take in oxygen and give off carbon dioxide through photosynthesis.

What 2 gases are recycled by the process of photosynthesis and cellular respiration?

The two gases that are recycled by the process of photosynthesis and cellular respiration are oxygen and carbon dioxide. In photosynthesis, plants take in carbon dioxide and release oxygen, while during cellular respiration, organisms take in oxygen and release carbon dioxide.

1996 4Runner ATP light?

The A/T P (automatic transmission park) indicator on the dash normally illuminates when the vehicle may be in danger of drifting, due to the transfer case being shifted into neutral. This (drift) can happen even when the transmission is in park - since the transfer case effectively disconnects the upper drivetrain, when shifted out-of-gear.

If the transfer case is properly shifted in H or L ranges (not neutral) and the indicator is illuminated, then there may be an adjustment needed in linkages or switch positions or even a malfunction in the circuit, such as a bad switch (i.e neutral safety, transfer indicator) or in the other associated electrical components.

The Toyota A340F transmission manual contains troubleshooting procedures for determining such malfunctions, including the false indication of an A/T P lamp, (visible on the dash combination meter).

What organisms obtain food almost entirely by autotrophic photosynthesis?

Plants, algae, and some bacteria are organisms that obtain food almost entirely through autotrophic photosynthesis. They are able to convert sunlight into energy through the process of photosynthesis, using chlorophyll to capture light energy and produce organic compounds like glucose.

What is the Name for turning green plants white by lack of light?

The term for turning green plants white due to a lack of light is "etiolation." This process occurs when plants are grown in darkness, causing them to become pale and elongated as they reach for light.

What are the 3 raw materials needed for erythrocyte?

The three raw materials needed for erythrocyte production are iron, vitamin B12, and folic acid. These nutrients are essential for the formation of hemoglobin, which is crucial for carrying oxygen in red blood cells.

What combines carbon dioxcide and water and traps energy in a cell?

Photosynthesis combines carbon dioxide and water, using sunlight to trap energy in the form of glucose in a cell.

Can daisies perform photosynthesis?

Yes, daisies have the ability to perform photosynthesis. Like all plants, they contain chlorophyll in their cells which allows them to convert sunlight, water, and carbon dioxide into energy in the form of sugars. This process is essential for their growth and survival.

From what substance is oxygen produced in photosynthesis?

Oxygen is produced in photosynthesis as a byproduct when water molecules are split during the light-dependent reactions in the chloroplasts of plant cells. This process releases oxygen as a waste product, which is then released into the atmosphere.

What raw materials in the extraction of iron?

The raw materials used in the extraction of iron are iron ore, coke (made from coal), and limestone. Iron ore is the primary source of iron, while coke is used as a reducing agent and fuel, and limestone helps to remove impurities from the iron ore during the smelting process.
