Primary Active Transport01:47

Primary Active Transport

198.3K
In contrast to passive transport, active transport involves a substance being moved through membranes in a direction against its concentration or electrochemical gradient. There are two types of active transport: primary active transport and secondary active transport. Primary active transport utilizes chemical energy from ATP to drive protein pumps that are embedded in the cell membrane. With energy from ATP, the pumps transport ions against their electrochemical gradients—a direction...

Primary and Secondary Growth in Roots and Shoots

60.5K
Vascular plants, which account for over 90% of the Earth’s vegetation, all undergo primary growth—which lengthens roots and shoots. Many land plants, notably woody plants, also undergo secondary growth—which thickens roots and shoots.

Primary Production01:06

Primary Production

25.2K
The total amount of energy acquired by primary producers in an ecosystem is called gross primary production (GPP). However, of this energy, producers use some for metabolic processes, and some is lost as heat, decreasing the amount of energy available to the next trophic level. The remaining usable amount of energy is called the net primary productivity (NPP). In terrestrial ecosystems, NPP is driven by climate, while light penetration and nutrient availability drive NPP in aquatic ecosystems.

Primary Distribution01:28

Primary Distribution

546
Primary distribution systems deliver electrical power from substations to consumers through various voltage classes, with 15-kV class voltages being predominant among U.S. utilities. Older 2.5- and 5-kV classes are being replaced by 15-kV primaries, while higher 25- to 34.5-kV classes are used in high-density urban areas and rural regions with long feeders. Three-phase, four-wire multigrounded systems are widely employed for balanced power delivery, using the neutral wire as a grounding point.

Properties of Enantiomers and Optical Activity02:24

Properties of Enantiomers and Optical Activity

21.7K
It is essential to understand the difference between chiral and achiral interactions and the implications thereof in optical activity and their applications. Just as our feet, which are chiral, interact uniquely with chiral objects, such as a pair of shoes, but identically with achiral socks, enantiomers of a molecule exhibit different properties only when they interact with other chiral media. An example of a significant implication from this facet is the phenomenon known as optical activity,...

Area of Science:

  • Neurology
  • Endocrinology
  • Ophthalmology

Background:

  • Hypoparathyroidism is a rare endocrine disorder characterized by insufficient parathyroid hormone production.
  • Common neurological complications include papilloedema and raised intracranial pressure.
  • Optic neuritis is an exceptionally rare manifestation of hypoparathyroidism.

Observation:

  • A 54-year-old male presented with symptoms consistent with classical optic neuritis.
  • The patient was diagnosed with primary hypoparathyroidism.

Findings:

  • The patient's optic neuritis was considered secondary to primary hypoparathyroidism.
  • This case represents a rare association between hypoparathyroidism and optic neuritis.

Implications:

  • This case underscores the need to investigate hypoparathyroidism in patients with unexplained optic neuritis.
  • Early diagnosis and management of hypoparathyroidism may prevent or mitigate neurological complications.
  • Further research is warranted to elucidate the pathophysiological mechanisms linking hypoparathyroidism and optic neuritis.
