52 chromosomes. Somatic cells (or body cells) all have a diploid number of chromosomes... its sex cells (or gametes) would have half the number (26).
When electrons of a chlorophyll molecule are raised to a higher energy level, they are transferred to an electron carrier. The correct answer is D, are transferred to an electron carrier.
Slow down or stop all together as enzymes are substances that speed up and help reactions without being used up themselves.
They are like catalysts(inorganic version of enzymes)
Answer: energy can be cycled in two directions
Explanation: The arrows show the direction of matter and energy flow and should be two
Answer:
Matrix, Mitochondrion, Kreb's cycle, Pyruvic acid
Explanation:
The above question illustrates aerobic cellular respiration, specifically the second stage called Kreb's cycle or Citric acid cycle. This process occurs in the inner membrane of the mitochondrion of eukaryotic cells called MATRIX.
It occurs when the pyruvic acid produced during Glycolysis (first stage of cellular respiration that occurs in the cytoplasm) is converted to Acetyl CoA in order to enter the citric acid cycle in the mitochondrion. The Acetyl CoA is then used in a series of reactions that comprises of reduction-oxidation, hydration, dehydration, and decarboxylation.
This reactions involving 8 steps converts the Acetyl CoA (from pyruvic acid) to 2 molecules of CO2, 1 molecule of GTP/ATP, and electron donors NADH2 and FADH2.
