Abstract

Vitamin A deficiency can cause health problems that affect vision, such as night blindness and xerophthalmia. One way to prevent this disease is by consuming foods rich in provitamin A, especially β-carotene. This study aims to discuss the role of bioactive compounds found in carrots (Daucus carota L.) in reducing the risk of xerophthalmia and night blindness by conducting a literature review, namely by analyzing various related scientific articles. Research shows that carrots are a fairly high source of β-carotene, which can be converted into vitamin A according to the body’s needs. Vitamin A can also play an important role in helping the formation of rhodopsin, which is needed for clear vision in dim light conditions. In addition, this vitamin is also important for maintaining the integrity and function of the eye’s epithelial tissue. Furthermore, β-carotene also has the ability to protect eye cells from damage caused by oxidation due to its antioxidant properties. Consuming carrots can help increase vitamin A levels in the body, prevent night blindness and xerophthalmia, and provide benefits for general eye health. Nutrition education, particularly the importance of consuming foods containing vitamin A, is needed to raise public awareness and prevent vitamin A deficiency.

Abstract

Jalur metabolisme energi merupakan proses biokimia fundamental yang sangat krusial untuk mempertahankan kehidupan di seluruh kerajaan hayati. Meskipun kerangka katabolik inti seperti glikolisis, siklus asam trikarboksilat (TCA), dan fosforilasi oksidatif terkonsevasi secara evolusioner, terdapat adaptasi fungsional, struktural, dan regulasi yang signifikan antara tumbuhan, hewan, dan mikroorganisme. Literatur review ini bertujuan untuk membandingkan mekanisme biokimia, kompartmentalisasi seluler, akseptor elektron akhir, serta fleksibilitas regulasi yang mengontrol bioenergetika pada ketiga kelompok organisme tersebut. Metode penulisan dilakukan melalui penelusuran pustaka tersistem pada jurnal-jurnal ilmiah bereputasi. Hasil kajian menunjukkan bahwa tumbuhan mengintegrasikan fotosintesis oksigenik dengan respirasi mitokondria, memanfaatkan enzim spesifik seperti alternative oxidase (AOX) untuk mengelola stres oksidatif. Hewan bergantung penuh pada respirasi heterotrofik dengan regulasi hormonal yang ketat untuk memenuhi kebutuhan energi metabolik jaringan spesifik. Sementara itu, mikroorganisme menampilkan keanekaragaman metabolik yang paling tinggi dengan jalur glikolisis alternatif (Entner-Doudoroff dan Pentosa Fosfat), respirasi anaerobik menggunakan akseptor anorganik non-oksigen, serta berbagai lintasan fermentasi. Kesimpulannya, divergensi enzimatis dan fleksibilitas katabolik antar-kingdom mencerminkan strategi adaptasi ekologis terhadap ketersediaan nutrisi dan oksigen.
