# What is the theoretical efficiency of photosynthesis?

## What is the theoretical efficiency of photosynthesis?

The photosynthetic efficiency is dependent on the wavelength of the light absorbed. Photosynthetically active radiation (400–700 nm) constitutes only 45% of the actual daylight. Therefore the maximum theoretical efficiency of the photosynthesis process is approximately 11%.

What is CHL photosynthesis?

Chlorophylls (Chls, Chl a and Chl b) are tetrapyrrole molecules essential for photosynthetic light harvesting and energy transduction in plants. Once formed, Chls are noncovalently bound to photosynthetic proteins on the thylakoid membrane.

### What is the enthalpy of photosynthesis?

+2814 kJ mol−1
(Enthalpy change is the negative of heat of combustion.) Hence the enthalpy change for the respiration reaction is −2814 kJ mol−1, and so the enthalpy change for the photosynthesis reaction is +2814 kJ mol−1.

How will you determine the rate of photosynthesis quizlet?

How can photosynthesis be measured? Directly: by the production of oxygen(counting bubbles) or the uptake of carbon dioxide (measuring pH of surroundings).

#### Which of the following equations correctly represent photosynthetic efficiency?

The photosynthesis equation is as follows: 6CO2 + 6H20 + (energy) → C6H12O6 + 6O2 Carbon dioxide + water + energy from light produces glucose and oxygen.

Why is photosynthesis not 100 efficient?

100% sunlight → non-bioavailable photons waste is 47%, leaving. 53% (in the 400–700 nm range) → 30% of photons are lost due to incomplete absorption, leaving. 37% (absorbed photon energy) → 24% is lost due to wavelength-mismatch degradation to 700 nm energy, leaving.

## How do you calculate chlorophyll a and b?

Total Chlorophyll (mg) in original tissue sample = Total Chlorophyll (mg/mL) x final volume (mL). Total Chlorophyll a (mg) in original tissue sample = Chlorophyll a (mg/mL) x final volume (mL). Total Chlorophyll b (mg) in original tissue sample = Chlorophyll b (mg/mL) x final volume (mL).

What is CHL in chemistry?

Chemical structures of chlorophyll (Chl) with IUPAC/IUBMB numbering for carbon atoms, and the directions.

### Is the equation for photosynthesis exothermic or endothermic?

endothermic
Photosynthesis is endothermic, and the necessary energy is supplied by the absorption of solar radiant energy. This energy can be released by carrying out the reverse of Equation 15.13. 1, a process which is exothermic. When we burn paper, wood, or dried leaves, the heat given off is really a stored form of sunlight.

Is photosynthesis exo or endothermic?

endothermic reaction
Photosynthesis requires energy to drive the chemical reaction. Photosynthesis is an endothermic reaction. This means it cannot occur without energy (from the Sun). The light required is absorbed by a green pigment called chlorophyll in the leaves.

#### How do you calculate the rate of photosynthesis GCSE?

In the table below, the Rate of photosynthesis = Number of bubbles produced per minute….Scientific calculations.

Distance Rate
20 cm 30
25 cm 17
30 cm 13

What are two ways to measure the rate of photosynthesis?

What are the different methods of measuring the rate of photosynthesis?

• Measuring the uptake of CO2.
• Measuring the production of O2.
• Measuring the production of carbohydrates.
• Measuring the increase in dry mass.

## Which of the following equation is summary of photosynthesis?

(D) 6CO 2 + 12H 2 O + Chlorophyll + Sunlight→ C 6 H 12 O 6 + 6CO 2 + 6H 2 O.

What is the correct equation of photosynthesis and respiration?

Connecting Cellular Respiration and Photosynthesis Notice that the equation for cellular respiration is the direct opposite of photosynthesis: Cellular Respiration: C6H12O6 + 6O2 → 6CO2 + 6H2O. Photosynthesis: 6CO2 + 6H2O → C6H12O6+ 6O.

### Is photosynthesis more efficient than solar panels?

Photosynthesis is less efficient than solar panels. According to the Wikipedia page on photosynthetic efficiency, typical plants have a radiant energy to chemical energy conversion efficiency between 0.1% and 2%. Most commercially available solar panels have more than 10 times this efficiency.

What is the formula of chlorophyll a?

C₅₅H₇₂O₅N₄MgChlorophyll a / Formula

#### What’s the formula of chlorophyll b?

C55H70MgN4O6
Chlorophyll B | C55H70MgN4O6 – PubChem.

What is the formula for chlorophyll b?

## What is the formula of chlorophyll d?

C54H70MgO6N4Chlorophyll d / Formula
