It is the sun.
The heat from the sun is important for the water cycle.
A.
The mitochondria is the site of the aerobic respiration in the eukaryotic organism. The mitochondria uses the glucose and the oxygen molecules to form the carbon dioxide, water and ATP (adenosine triphosphate) molecule.
The equation for the aerobic respiration is given below:
Glucose + oxygencarbon dioxide + water
All the reaction takes place in the mitochondria, Hence, the givenb lanks can be filled as follows:
1. glucose
2. oxygen
3. carbon dioxide
4. water
5. ATP
B.
The process shown in the figure is aerobic respiration. In the given figure, the mitochondria is shown, the mitochondria is the site of aerobic respiration. The mitochondria obtain the glucose and the oxygen molecule present in the cytoplasm of the cell. The complete aerobic respiration takes place in three steps glycolysis, Kreb cycle and electron transport. In the glycolysis, the glucose is converted into pyruvate. In the Krebs cycle, the pyruvate is oxidised in acetyl-CoA, which undergoes a sequence of reaction giving out ATP from ADP. In the electron transport chain, the NADH as well as succinate, which is formed in the citric acid cycle or Krebs cycle are oxidized, which provides the energy to power ATP synthase (the enzyme involved in the creation of storage of ATP).
Its d because they are asking about whats expressing
What happens at the level of the muscle proteins during muscle contraction is that the myosin-binding sites are exposed, and due to insufficient ATP present, myosin binds to actin to begin cross-bridge cycling.
<h3>What is muscle contraction?</h3>
Muscle contraction is defined as the activation of tension-generating sites within muscle cells.
During muscle contraction, the myosin-binding sites are exposed, and due to insufficient ATP present, myosin binds to actin to begin cross-bridge cycling.
Also, as the muscle contracts, thick filaments shortens and thin filaments slides.
Thus, what happens at the level of the muscle proteins during muscle contraction is that the myosin-binding sites are exposed, and due to insufficient ATP present, myosin binds to actin to begin cross-bridge cycling.
