The proton proton chain consists of three chains:
85.9 % PP1) H+H -> 2H -> 2H-(e+)-(v) + H -> 3He
3He + 3He -> 4He + 2H
14 % PP2) 3He + 4He -> 7Be -> 7Be-(e-)-(gamma) -> 7Li -> 7Li-(v)+H -> 4He + 4He
0.1 % PP3) 7Be + H -> 8B - (gamma) -> 8Be + (e+) + (v) -> 4He + 4He
where i have used the notations:
- v for neutrino
- (gamma) for gamma particle
- e+ for positron
- e- for electron
- x% means it accounts for x% of the total conversion of H -> He
The three steps of the proton-proton chain are: 1) initiating reaction where two protons fuse to form a deuterium nucleus, 2) the deuterium nucleus combines with another proton to form a helium-3 nucleus, and 3) two helium-3 nuclei fuse to produce a helium-4 nucleus and release two protons.

What are the three steps of cellular metabolism?
Cellular metabolism consists of three main steps: glycolysis, the citric acid cycle (also known as the Krebs cycle), and oxidative phosphorylation (electron transport chain). These steps are essential for generating ATP, the cell's main energy source, from nutrients like glucose.
What steps of respiration produces the most energy for the organism?
electron transport chain
Why is PCR called a chain reaction?
PCR is called a chain reaction because it involves the repeated cycling of three main steps (denaturation, annealing, and extension) to exponentially amplify a specific DNA sequence. Each round of these steps creates new copies of the target DNA, leading to a chain reaction that greatly increases the amount of DNA available for analysis.
What makes up the second and higher steps in a food chain?
The second and higher steps in a food chain typically consist of consumers, such as herbivores and carnivores, that feed on other organisms. These organisms further transfer energy up the food chain by eating lower trophic level creatures. Each step in the food chain represents a transfer of energy from one organism to another.
Which steps in aerobic cellular respiration require oxygen?
The citric acid cycle and the electron transport chain are the steps in aerobic cellular respiration that require oxygen. Oxygen is the final electron acceptor in the electron transport chain, where it helps generate ATP by facilitating the transfer of electrons from NADH and FADH2 to oxygen.
How many intermediate steps should a distribution chain have?
steps in distribution chain company
What are the three steps to a chain reaction?
The three steps to a chain reaction are initiation, propagation, and termination. Initiation involves the initial trigger or activation of the reaction. Propagation is the process by which the reaction continues to spread through the system. Termination signifies the end of the reaction as the reactants are consumed or conditions change.
What are the three steps of cellular metabolism?
Cellular metabolism consists of three main steps: glycolysis, the citric acid cycle (also known as the Krebs cycle), and oxidative phosphorylation (electron transport chain). These steps are essential for generating ATP, the cell's main energy source, from nutrients like glucose.
What makes up respiration?
It occurs in three steps 1. Glycolysis, 2. Kerbs cycle, 3. Electron transport chain
How do farmers reduce the steps of the food chain?
they eat
What are the steps to the under water food chain?
pigs
What are 3 major steps in cellular respiration?
Actually there are 4 steps of aerobic cellular respiration Glycolysis, Oxidative decarboxylation of pyruvate, kreb's cycle, electrton transport chain
What are the two steps in aerobic respiration that produce ATP?
The two steps in aerobic respiration that produce ATP are glycolysis and oxidative phosphorylation. Glycolysis generates a small amount of ATP directly, while oxidative phosphorylation, which occurs in the mitochondria, produces the majority of ATP through the electron transport chain and ATP synthase.
What are the steps to a chain reaction?
A chain reaction typically involves three steps: initiation, propagation, and termination. During initiation, the reaction is triggered by an initial event. In propagation, products from the initial reaction continue to react, creating more products. Termination occurs when the reaction eventually stops due to the depletion of reactants or other factors.
When was Three Steps North created?
Three Steps North was created in 1951.
When was Three Steps in the Dark created?
Three Steps in the Dark was created in 1953.
When was Three Steps to the Gallows created?
Three Steps to the Gallows was created in 1953.
