<span>The answer is Each stage produces ATP, but only the first stage occurs in the cytoplasm. Cellular respiration consists of three stages: 1. Glycolysis which takes place in the cytoplasm, 2. Krebs cycle which takes place in the mitochondria, and 3. Electron transport chain which takes place in the mitochondria. During each step, ATP is produced.</span>
Answer:
c
Explanation:
Sexual: meiosis, crossing over, and random assortment of chromosomes; pollination
The electron transport chain of the cellular respiration process produces maximum ATP.
There are three parts of cellular respiration:
Glycolysis, which produces 2 ATP.
Krebs cycle, which does not produce any ATP. It produces only the raw materials for ATP production.
Oxidative phosphorylation, which involves the electron transport chain that produces maximum ATP. It takes one NADH molecule via Channel 1 to produce 2.5 ATP and one FADH2 molecule via channel 2 to produce 1.5 ATP, for a total of 34 ATP.
Answer:
Replicated chromosomes at metaphase I = 66
Sister chromatids at metaphase I = 66 x 2 = 132
Sister chromatids at prophase II = 66
Chromosomes in each sperm cells = 33
Explanation:
Metaphase I of meiosis I would have 66 replicated chromosomes in the testicular cells of the bird. Each of the replicated chromosomes would have two sister chromatids. So, a total of 66 replicated chromosomes would have 66 x 2 = 132 sister chromatids.
Due to segregation of homologous chromosomes towards opposite poles in anaphase I, each daughter cell formed by the end of meiosis I would have 33 replicated chromosomes. So, each of the daughter cells would have a total 33 x 2 = 66 sister chromatids at prophase II.
Since meiosis II maintains the chromosome number, each sperm cell formed by the end of meiosis II would have 33 chromosomes.
The statement above is TRUE.
The electrochemical gradient in the chloroplast is a gradient of electrochemical potential of ions which move across the membrane of the chloroplast during the photosynthesis process. The proton gradient across the thylakoid membrane drives the ATP synthesis during photosynthesis.
