Abstract

Tempeh is a traditional Indonesian fermented food produced through the activity of microorganisms, particularly Rhizopus sp. This study aimed to analyze the role of Rhizopus sp. in the fermentation of soybeans into tempeh. This laboratory experimental research was conducted at the Biology Education Laboratory, Faculty of Tarbiyah and Teacher Training, Universitas Islam Negeri Sumatera Utara. Fermentation was carried out at a temperature of 28–32°C for 36–48 hours using tempeh starter. The observed parameters included the growth of Rhizopus sp. mycelium and the physical characteristics of tempeh. The results showed that Rhizopus sp. played an important role in producing tempeh with a compact structure, bright white color, homogeneous texture, and characteristic aroma.

Abstract

Metabolism in biology learning is one of the complex concepts because it involves various biochemical processes occurring in living cells. Students often have difficulty understanding this topic because it is abstract and contains many reaction stages that must be learned in sequence. This study aims to examine the application of biochemical concepts in biology learning to improve students understanding of metabolism. The method used is a literature review by analyzing relevant scientific sources. The results show that the application of biochemical concepts can help students understand metabolic processes more clearly by linking chemical reactions with biological functions at the molecular level. In addition, the use of visual and technology based learning media also supports better student understanding. In conclusion, the integration of biochemical concepts in biology learning is effective in improving students understanding of metabolism.

Abstract

This study aims to examine the role of coenzyme Q10 (CoQ10) in energy metabolism and cell stability through a Systematic Literature Review (SLR) approach. Coenzyme Q10 is an essential component in the electron transport chain in mitochondria that plays a role in the production of adenosine triphosphate (ATP) as the main energy source of cells. In addition, CoQ10 also has antioxidant activity that can protect cells from damage due to oxidative stress. The method used in this study is SLR by analyzing two relevant scientific articles, namely those discussing the physiological and pharmaceutical aspects of CoQ10. The results of the study indicate that CoQ10 has a dual role, namely as an energy producer and cell protector. In the pharmaceutical context, the use of a liposome-based delivery system has been shown to increase the stability and bioavailability of CoQ10. A critical analysis of both articles shows that the integration of biological approaches and pharmaceutical technology is crucial to optimize the benefits of CoQ10. Thus, this study provides a comprehensive understanding of the importance of coenzyme Q10 in life and its potential in the development of coenzyme-based therapies in the health sector.

Abstract

Enzymes are biocatalysts that play an important role in various metabolic processes of living organisms. Enzyme activity is influenced by several environmental factors, especially pH and temperature. This article aims to analyze and compare the findings of eight recent biochemical journals discussing the effect of pH and temperature on enzyme activity. The method used in this study was a literature review by examining relevant scientific journals published in recent years. The results showed that each enzyme has different optimum pH and temperature conditions depending on the type of enzyme and its microbial source. Excessive temperature may cause enzyme denaturation, while unsuitable pH can alter the structure of the enzyme’s active site and reduce its catalytic activity. Based on the comparison of several studies, it can be concluded that pH and temperature are the main factors affecting enzyme stability and activity in biochemical reactions.
