# What happens when cells are connected in series?

## What happens when cells are connected in series?

Cells in Series Connection In series, cells are joined end to end so that the same current flows through each cell. In case if the cells are connected in series the emf of the battery is connected to the sum of the emf of the individual cells.

## When two or more electric cells are connected?

So, the combination of two or more cells is called a battery.

What happens to current when cells are connected in parallel?

Cells connected in Parallel Combination If equivalent internal resistance is less than external resistance then current in circuit is equal to current produced by a single cell.

### What is the path of electrons from NADH through the electron transport chain?

The path of electron flow is NADH → NADH dehydrogenase complex → ubiquinone → cytochrome b-c1 complex → cytochrome c → cytochrome oxidase complex → molecular oxygen (O2). The respiratory enzyme complexes couple the energetically favorable transport of electrons to the pumping of H+ out of the matrix.

### When two cells are connected in series they are connected?

A collection of two or more cells which are connected in series is called A Battery. A battery is an energy source that converts chemical energy to electrical energy. It is otherwise known as Electrochemical Cell.

When cells are connected in series What increases?

(B) Series combination: When cells are connected in series combination the negative terminal of one cell is connected to the positive terminal of the other cell and vice-versa. According to Kirchhoff’s law, when the cells are connected in series combination the voltage across the cells can be increased.

#### What is formed when two or more cells are joined together?

Just as cells join together to form tissues, different tissues join together to form organs. An organ is a structure made up of two or more tissues that work together to carry out a specific job. Ex: Your heart, is an organ made up of muscle tissue, blood tissue, and nerve tissue.

#### When two or more cells are connected to each other by opposite terminals then it is called as?

Such a combination is called a battery.

When cells are connected in parallel then the current increases or decreases?

Therefore when cells are connected in parallel, the voltage remains the same, and internal resistance decreases, hence the current increases.

## What happens to NADH in the electron transport chain?

The events of the electron transport chain involve NADH and FADH, which act as electron transporters as they flow through the inner membrane space. In complex I, electrons are passed from NADH to the electron transport chain, where they flow through the remaining complexes. NADH is oxidized to NAD in this process.

## How do NADH molecules contribute to electron transport?

NADH and FADH2 made in the citric acid cycle (in the mitochondrial matrix) deposit their electrons into the electron transport chain at complexes I and II, respectively. This step regenerates NAD+ and FAD (the oxidized carriers) for use in the citric acid cycle.

How are two cells connected to each other?

Cell junctions The three main ways for cells to connect with each other are: gap junctions, tight junctions, and desmosomes. These types of junctions have different purposes, and are found in different places.

### How are electrons pushed out of a cell?

Each electron is pushed by an internal electric field that has been created in the factory in each cell. The flow of electrons pushed out of the cell by this internal field is what we call the “electric current”. As long as there is light flowing into the cells, there are electrons flowing out of the cells.

### How are two electrical devices connected in a circuit?

When there are two or more electrical devices present in a circuit with an energy source, there are a couple of basic means by which to connect them. They can be connected in series or connected in parallel.

What are the two types of electrical connections?

Two Types of Connections. When there are two or more electrical devices present in a circuit with an energy source, there are a couple of basic means by which to connect them. They can be connected in series or connected in parallel.

#### How are cell junctions linked to the extracellular matrix?

Many cells in tissues are linked to one another and to the extracellular matrix at specialized contact sites called cell junctions. Cell junctions fall into three functional classes: occluding junctions, anchoring junctions, and communicating junctions.
