In the citric acid cycle, also referred to as the Kreb’s Cycle, the enzyme responsible for catalyzing oxidative decarboxylation reactions is α-Ketoglutarate dehydrogenase. This irreversible oxidative decarboxylation step generates NADH (equivalent to 2.5 ATP) and restores the 4C chain (excluding CoA).
Response: B. Shrubland
The thornscrub ecosystem exists between the Sonoran and Chihuahuan Deserts. It characterizes a typical shrubland comprising smaller trees like velvet mesquite and shrubs such as Catlaw acacia and cactus commonly found in the Sonoran Desert. The thornscrub shrubland showcases distinct wet and dry seasons, allowing for the growth of both annual and perennial herbs. Consequently, the vegetation is influenced by alternating wet and dry periods.
Answer:
Brachydactyly and Huntington's are phenotypic conditions that occur when a person possesses one or two dominant alleles for those traits.
John's father has Huntington's disease but does not have brachydactyly, which means his genotype is Hh/bb.
John's mother, who is healthy and has brachydactyly, likely has a genotype of hh/BB or hh/Bb.
