Why is the pH of 4.6 important in the food industry The pH of 4.6 is the critical limit for food since pH is a critical factor for intrinsic control. 4.6 or below prevents the growth of spores and toxin formation. Toxins are produced from vegetative cells. This pH defines between the high/low acid food Compare contrast Intrinsic factors versus extrinsic factors associate with food spoilage. Intrinsic factors are factors related to the food itself whereas the extrinsic factors are a part...

MIC 102unit 5-2 Exam Questions with Correct Answers The stable association of one organism with another is called - Answer-Blank 1: symbiosis or symbiotic Historically, the smaller organism in a symbiotic relationship was termed the symbiont and the larger organism the host. Currently, these two organisms are now regarded as . - Answer-partners A symbiotic relationship in which each partner receives some benefit, but each partner can also live independently is called . - Answer-coopera...

13.1 Describe the difference between catabolism and anabolism -catabolism: the cellular breakdown of large molecules into smaller molecules, releasing energy -anabolism (biosynthesis): building up of complex biomolecules from smaller precursors 13.2 Review Table 13.1 for how microbes obtain energy. Explain the role of energy carriers ATP, NADH, and FADH2 ATP: carrier and storage of energy NADH: donate e- to the ETS--product of glycolysis and TCA FADH2: donate e- to the ETS--product o...
