Which of the following would not characterize allopathic selection?
Answer:
yes
Explanation:
according to model 2 what is the source of replacement electrons for those released from photosystem I
In accordance with Model 2, the source of the replacement electrons for those released from Photosystem 1 are electrons from Photosystem 2.
The energy store molecule ATP and the reduced electron carrier NADPH are two molecules produced by the light-dependent processes that are required for the next phase of photosynthesis. The thylakoid membranes of organelles referred to as chloroplasts are where the light responses occur in plants.
The light processes are crucially influenced by photosystems, sizable protein and pigment (light-absorbing molecule) complexes that are designed to capture light.
The two different kinds of photosystems are the PSI and the PSII (PSII).
Numerous pigments that aid in the absorption of light energy may be found in both photosystems, along with a unique pair of chlorophyll molecules that are located at the core (reaction center) of the photosystem. The unique pair of photosystem I is referred to as P700, while the unique pair of photosystem II is referred to as P680.
Energy is transferred from pigment to pigment inside of photosystem II when light is absorbed by one of the numerous pigments inside. This process continues until the reaction center is reached. An electron's energy is raised there, where it is transmitted to P680. An acceptor molecule receives the high-energy electron, which is then exchanged for an electron from water. The oxygen we breathe is released as the water splits.
When the electron reaches photosystem I, it joins the reaction center's P700 unique pair of chlorophylls. The electron in P700 is raised to a very high energy level and transferred to an acceptor molecule when light energy is absorbed by pigments and sent inward to the reaction site. The lost electron of the exceptional pair is replaced by an electron from PSII.

Answer:
In photosynthesis, reactants such as carbon dioxide and water are used to create products such as glucose and oxygen. In cellular respiration, glucose and oxygen are used as reactants to create products such as carbon dioxide and water. The organelle involved in photosynthesis is the chloroplast, which contains chlorophyll and other pigments that absorb sunlight to convert it into chemical energy. The organelle involved in cellular respiration is the mitochondria, which converts the chemical energy in glucose and oxygen into a form that cells can use. Photosynthesis and respiration are a cycle because they are interconnected and dependent on each other. The glucose produced during photosynthesis is used as a reactant in cellular respiration, while the oxygen produced during photosynthesis is used as a reactant in cellular respiration. The carbon dioxide and water produced during respiration are used as reactants in photosynthesis.

explain how the calcium transient differs between cardiac and skeletal muscle and how this influences contractility
The calcium transient is a process that occurs in both cardiac and skeletal muscle, but it differs in some key ways.
In cardiac muscle, the calcium transient is triggered by the release of calcium ions from the sarcoplasmic reticulum (SR), which is a specialized organelle that stores calcium ions. This release of calcium ions causes a brief increase in the concentration of calcium ions in the cytoplasm, which in turn triggers muscle contraction.In skeletal muscle, the calcium transient is triggered by the release of calcium ions from the SR, but it is also dependent on the release of calcium ions from the extracellular space. The release of calcium ions from the SR is triggered by the action potential that travels along the muscle fiber, while the release of calcium ions from the extracellular space is triggered by the binding of the neurotransmitter acetylcholine to the muscle cell membrane.What are the difference in both?The difference in the calcium transient between cardiac and skeletal muscle influences contractility, or the ability of the muscle to contract.
Cardiac muscle contractility is largely dependent on the amount of calcium ions released from the SR, while skeletal muscle contractility is dependent on both the amount of calcium ions released from the SR and the amount of calcium ions released from the extracellular space.
Additionally, cardiac muscle has a slower rate of relaxation, which allows for a more sustained contraction. Skeletal muscle has a faster rate of relaxation, which allows for a more rapid contraction and relaxation cycle.
