H-zone in a contracted sarcomere differ from that of a relaxed sarcomere . Yes its true because H-zone is narrower in contracted sarcomere. The functional unit of striated muscle is sarcomere. Sarcomere is the very basic unit of skelatal muscle. Between two Z line sarcomere is the repeated unit .Hence we can say that H-zone in a contracted sarcomere differ from that of a relaxed sarcomere.
<em>Answer:</em>
<em>The penicillin wouldn't affect the Archaea because it prevents the cross linking of peptidoglycan- Archaea don't have this compound in their cell walls.</em>
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 + oxygen
carbon 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).
