Question: During the Krebs cycle: a. NADH is oxidized. b. ATP is produced. c. pyruvate is produced. d. acetyl-CoA gains a carbon to form pyruvate. Krebs Cycle: The Krebs cycle is a set of processes in which ace
In rat models of mammary carcinogenesis, the highest incidence of carcinomas occurs when the animals are exposed to carcinogens during puberty (typically postnatal day 50). Gene expression analysis of rat mammary gland in Sprague-Dawley rats revealed a consistent down-regulation of Krebs cycle genes...
In the citric acid cycle (Krebs cycle), how many of each energy-rich molecule is produced? 1) When 13 molecules of pyruvic acid are broken down completely to CO2 and H2O in the presence of oxygen, how many molecules of ATP will be produced? 2) When 16 acetyl Co...
To solve the question regarding the formation of FADH2 in the Krebs cycle, we can analyze each option step by step.1. Understand the Krebs Cycle: The Krebs cycle, also known as the citric acid cycle or TCA cycle, is a series of
This phenotype was not due to a change in mitochondrial mass or number, but rather due to decreased mitochondrial function, as it could be rescued by inhibition of pyruvate dehydrogenase kinase 4 (PDK4), which diverts pyruvate from the Krebs cycle to the production of lactate [64]. Further...
Memories are stored in the brain as cellular ensembles activated during learning and reactivated during retrieval. Using the Tet-tag system in mice, we label dorsal dentate gyrus neurons activated by positive, neutral or negative experiences with channel
2.1. The estrous cycle The estrous cycle of mammalian species consists of a follicular (proliferative) and a luteal (secretory) phase. In cattle, there are two to three follicular waves, which are preceded by an increase in follicle stimulating hormone (FSH) [23]. Stimulated by estrogens from...

Despite obesity being a predisposing factor for pancreatic β-cell dysfunction and loss, the mechanisms underlying its negative effect on insulin-secreting cells remain poorly understood. In this study, we identify an islet-enriched long non-coding RNA (
