Production and Problems - ATP - Adenosine Triphosphate

Often, special miracle products are touted by salesmen for use to prevent "stress" and that routine sprays will improve yield and quality. Plants under stress are most likely to have problems related to temperature or light rather than fertilizer. In many research trials with field vegetables, it has been shown that routine shot-gun foliar sprays do not increase yield or enhance quality. In fact, many studies show decreases in yield from these foliar sprays.

Explain how ATP is produced by electron transport chains during photosynthesis?


Two three carbon sugars called Pyruvic Acid are formed.
Investment stage-adding ATP
Energy payoff phase-acquiring ATP, NADH, Pyruvate
Takes place in cytoplasm of a cell
First step in cellular respiration
Glucose → 2 Pyruvic Acid + 2 ATP + 2 NADH
Very Fast, Small Energy, NAD’s can be used up and then ATP production stops
Oxygen (O2) NOT needed - Anaerobic

ATP production during photosynthesis


Once the electrochemical storage is great enough of H+, chemiosmosis or the ATP Synthesis allows H+ to pass through creating a field that will phosphorylate ADP in ATP.
32 or 34 ATP are produced in the ETC.

Krebs Cycle or Citric Acid Cycle
Occurs in Matrix of the Mitochondria
Pyruvic Acid from Glycolysis enters Matrix of the Mitochondria and is changed into actetyl CoA.
Pyruvic Acid broken down in a series of energy-extracting reactions
Controlled release of energy-oxidation of CO2.
Krebs Cycle passes NADH and FADH2 to electron transport chain
NADH and FADH2 used in electron transport to make more ATP
The Krebs Cycle must spin twice for each of the start pyruvic acid molecules.
Results
4 CO2, 6 NADH, 2 FADH2 and 2 ATP in the Krebs Cycle

Review Glycolysis-
The Breakdown of Glucose into two molecules
of pyruvic acid.
Produces 2 ATP
Glycolysis occurs in the Cytoplasm
If NO Oxygen present then to fermentation (anaerobic)
If Oxygen is present then finishes cellular respiration (aerobic).

The normal level of CO2 in the atmosphere is about 350 ppm. Research on many crops has shown that if the ambient level of CO2 is increased to 800 to 1000 ppm, increased plant growth and yield will result. Injection of CO2 is a standard practice in winter greenhouse vegetable production in northern climates. In these climates, high CO2 levels can be maintained because the greenhouses are closed during the winter. In Florida, CO2 injection is not as efficient as in northern climates because of the large amount of ventilation required, even in winter.

Manganese functions in several enzymatic reactions that involve the energy compound adenosine triphosphate (ATP). Manganese also activates several enzymes and is involved with the processes in the electron transport system in photosynthesis.

The reaction is mediated by an oxygen-sensitive enzyme nitrogenase and requires energy, as indicated by the consumption ofadenosine triphosphate (ATP ).This complex process is carried out by nitrogen-fixing bacteria present in the soil.

Sometimes petioles and plant leaf midribs on young leaves of full-grown plants show minor purpling. This often occurs in late fall when temperatures are reduced. This is probably not related to P deficiency since it occurs on young leaves. It is probably more related to increased levels of anthocyanin pigment expressed in the leaves under cool temperatures. This will not cause problems and will disapear under warmer conditions.

Chemistry for Biologists: Respiration

The form in which N is absorbed has an effect on the media pH. As NH4is absorbed, the plant releases H+ ions to maintain electrical balance, and therefore, the pH drops. As NO3is absorbed, the pH increases due to presence of increased amounts of OH-ions. Uptake of N, therefore, can explain some of the fluctuations sometimes seen in the pH of the growth media. Nitrogen is a very mobile element in the plant and deficiency symptoms therefore show up first on the lower leaves. Symptoms consist of a general yellowing (chlorosis) of the leaves. On tomatoes, there might be some red coloration to the petioles and leaf veins. If the problem persists, leaves will drop from the plant.
