Trusha and Aarya, both engaged in their biology studies, recently worked through multiple-choice questions covering cellular respiration, glycolysis, the Krebs cycle, and fermentation. During their discussion, Aarya encountered some errors concerning glycolysis products and the functions of co-enzymes within the Krebs cycle, which Trusha promptly clarified. Trusha then advised Aarya to thoroughly review these complex biological processes, with a particular emphasis on electron and proton transfers, in anticipation of their next lesson.

Trusha tutored Hunter in Hindi, focusing on conversational skills and cultural understanding. The lesson also prepared him for discussions related to his upcoming trip to India and his relationship with Punima's family. For homework, Hunter was assigned to translate sentences about flight booking and discussing his relationship into Hindi. Their next lesson is scheduled for Friday to review these translations and continue practicing Hindi.

Trusha and Beth discussed ecological relationships including mutualism, parasitism, interdependence, and competition. Beth analyzed a food web, identified different types of consumers, and explored the impact of population changes within the web. Homework was assigned to define food webs and food chains, and OCR exam questions were reviewed.

The learners worked on problems related to limiting reagents using a sandwich analogy and then moved on to heat change calculations using the formula Q=m*c*ΔT. One student, a resident of Queens, practiced calculating heat changes for different substances and explored the relationships between heat change, mass, specific heat, and temperature change. They will continue with the remaining questions in the next lesson and scheduled a class before Sunday.

Trusha assisted a university student from UCLA in practicing electron configurations for various elements and ions, including chlorine, sodium, and oxygen. The student worked on determining the number of protons, neutrons, and electrons in these species, and also learned that noble gases cannot be simplified in electron configurations. Trusha sent additional practice questions in the chat.

Trusha and Amit, both pursuing biology at UCLA in Tinseltown, recently had a lesson where they reviewed cell signaling, various types of cell communication, and the functions of cell organelles. They also clarified the roles of secondary messengers and kinases in cell signaling pathways. A worksheet was assigned for homework, with the answer key to be provided later. In a subsequent lesson, their focus shifted to enzymes, discussing their function as biological catalysts, essential terminology like substrate, active site, and the enzyme-substrate complex, the induced fit model, and different forms of enzyme inhibition. Amit was specifically tasked with reviewing irreversible inhibition and competitive inhibitors for their next lesson, which is scheduled for Thursday at 5:30.
