Session 2 cellular processes
Ap bio – fall review session
Cells, like humans, are unable to produce energy unless they can find a source in their surroundings. Unlike humans, who look for energy in the form of fossil fuels to power their homes and companies, cells look for it in the form of food molecules or sunlight. The Sun is, in reality, the ultimate source of energy for almost all cells, since photosynthetic prokaryotes, algae, and plant cells harness solar energy and use it to produce the complex organic food molecules that other cells depend on for the energy they need to maintain growth, metabolism, and reproduction (Figure 1).
Sugars and fats are only two examples of cellular nutrients. These molecules must move through the cell membrane to provide energy to the cell, which acts as a barrier but is not impenetrable. The plasma membrane, like the exterior walls of a home, is semi-permeable. Various proteins that span the cell membrane allow specific molecules into the cell in the same way that doors and windows allow necessities to reach the building, though they may require some energy input to do so (Figure 2).

The aim of this tutorial is to give you hands-on experience with modeling software tools that are well-suited to studying various types of cellular processes. This tutorial will focus on methods for studying models of regulatory versus metabolic systems, which use different formalisms and are seldom presented together.
The visualization and study of the dynamics of biochemical and biological processes can be done using logical modeling, which is a computational approach. One of the most attractive characteristics of logical models is their scalability and ease of implementation. Logical models have grown in popularity in the computational biology community, thanks in part to these characteristics. As a result, various techniques and software tools for the creation, simulation, and analysis of logical models and their variants (Boolean, multilevel, deterministic, stochastic, and so on) to answer various biological questions have been developed.

The robustness of neuroblast migration in C. elegans larvae in the face of genetic and environmental variation is the subject of a new study. The four writers of the paper give us more information about the story in an interview.
Early-career researchers will deliver their papers and have the opportunity to digitally network with the developmental biology community afterward as part of our popular webinar series, which will run through 2021. Camille Curantz explains how cell structure and motility influence bird feather patterning.

Tumor cells have 60-80 mutations that allow them to proliferate indefinitely and make them immune to most current therapies. Disturbances in essential cellular processes including apoptosis and senescence are two hallmarks of tumorigenesis and treatment resistance. Our lab’s main aim is to dissect the molecular components that regulate cell death and cellular senescence in order to identify possible targets and enhance cancer diagnosis and treatment.
To this end, we use molecular and cell biology, biochemistry, and immunology techniques such as RNA interference, gene and protein expression profiling, live-cell imaging, and whole animal models to achieve our objectives.
