Your question was incomplete (please check below the full content). The evidence that supports the prokaryotic origins of mitochondria and chloroplasts do not include multiple DNA copies associated with inner membranes.

<h3>What is organellar DNA?</h3>

The organellar DNA is the genome contained within mitochondria and chloroplasts, which is independent of nuclear eukaryotic DNA.

The organellar DNA contains multiple DNA molecules, which are found in association with the inner membrane, ant is not found in prokaryotic life forms.

The complete question in this case is: "Evidence that supports the prokaryotic origins of mitochondria and chloroplasts are the presence of mitochondria, a eukaryote engulfing prokaryotic photosynthetic cells, and non-photosynthetic eukaryotes, EXCEPT."

The endosymbiotic theory states that mitochondria and chloroplasts evolved from prokaryotic microorganisms that entered into a primitive eukaryotic cell.

This theory is supported by certain features of mitochondria and chloroplasts such as a similar size to prokaryotes.

In conclusion, evidence do not include the arrangement of the organellar DNA.

Cell respiration begins with
irinina [24]

Answer:

Cell respiration begins with Glycolysis .

Explanation:

Glycolysis  is the first and initial step in the cellular respiration. Cellular respiration is the anaerobic process, which takes place in cytosol of the cells. Two molecule of pyruvate(CH3COCOO-) are formed from 1 molecule  of  glucose(C6H12O6)through glycolysis. The  NADH and  ATP are high energy molecules formed when the free energy are released. It is the process which takes place through a series of ten enzyme catalysed reactions. 10 enzymes are required to break down the sugar molecule. It occurs in cytoplasm.

Using the sliding flament theory, explain (or draw) the process of sarcomere shortening. Start from the point where calcium woul
Arte-miy333 [17]

Answer:

  1. Calcium binds to troponin C
  2. Troponin T moves tropomyosin and unblocks the binding sites
  3. Myosin heads join to the actin forming cross-bridges
  4. ATP turns into ADP and inorganic phosphate and releases energy
  5. The energy is used to impulse myofilaments slide producing a power stroke
  6. ADP is released and a new ATP joins the myosin heads and breaks the bindings to the actin filament
  7. ATP splits into ADP and phosphate, and the energy produced is accumulated in the myosin heads, starting a new cycle
  8. Z-bands are pulled toward each other, shortening the sarcomere and the I-band, producing muscle fiber contraction.

Explanation:  

In rest, the tropomyosin inhibits the attraction strengths between myosin and actin filaments. Contraction initiates when an action potential depolarizes the inner portion of the muscle fiber. Calcium channels activate in the T tubules membrane, releasing <u>calcium into the sarcolemma.</u> At this point, tropomyosin is obstructing binding sites for myosin on the thin filament. When calcium binds to troponin C, troponin T alters the tropomyosin position by moving it and unblocking the binding sites. Myosin heads join to the uncovered actin-binding points forming cross-bridges, and while doing so, ATP turns into ADP and inorganic phosphate, which is released. Myofilaments slide impulsed by chemical energy collected in myosin heads, producing a power stroke. The power stroke initiates when the myosin cross-bridge binds to actin. As they slide, ADP molecules are released. A new ATP links to myosin heads and breaks the bindings to the actin filament.  Then ATP splits into ADP and phosphate, and the energy produced is accumulated in the myosin heads, which starts a new binding cycle to actin. Finally, Z-bands are pulled toward each other, shortening the sarcomere and the I-band, producing muscle fiber contraction.
