Cardiac output is defined as the quantity of blood pumped by the heart in one minute. It is represented by the formula:

Cardiac output = Stroke volume × Heart rate

Where,

Stroke volume is defined as the quantity of blood pumped from the left ventricle of the heart in one systolic contraction.

It can be calculated using the formula:

Stroke volume = End-diastolic volume − End-systolic volume

Given:

Heart rate = 70 rpm

End-diastolic volume = 135 ml

End-systolic volume = 65 ml

The stroke volume can be calculated as follows:

Stroke volume = End-diastolic volume − End-systolic volume

= 135 − 65

= 70 ml

Now, substituting the values of stroke volume and heart rate in the formula of cardiac output, we get:

Cardiac output = Stroke volume × Heart rate= 70 × 70= 4900 ml/min

Therefore, the cardiac output is 4900 ml/min when heart rate is 70 rpm, end-diastolic volume is 135 ml and end-systolic volume is 65 ml.

Multiple sites of DNA replication can exist inside the cell due to the presence of multiple replication origins on the DNA molecule.

DNA replication is a fundamental process in which the cell duplicates its genetic material. For efficient replication, cells possess multiple replication origins along their DNA molecules. These origins are specific DNA sequences where the replication machinery assembles and initiates the replication process.

The presence of multiple replication origins enables simultaneous initiation of DNA replication at different points along the DNA molecule. This spatial distribution of origins allows for the efficient and timely replication of the entire genome.

During the S phase of the cell cycle, when DNA replication occurs, each replication origin recruits a complex set of proteins that form the replication machinery. These proteins initiate the unwinding of the DNA double helix, synthesis of new DNA strands, and eventually the formation of two complete copies of the original DNA molecule.

Having multiple replication origins ensures that the large and complex genomes of eukaryotic cells can be replicated in a timely manner. It increases the speed and efficiency of DNA replication by allowing multiple replication forks to progress simultaneously, covering larger sections of DNA simultaneously.

Moreover, the presence of multiple replication origins provides a mechanism for cells to handle potential obstacles during replication, such as DNA damage or regions with tightly bound proteins. If one replication fork encounters an obstacle, other replication forks can continue to progress, ensuring the completion of DNA replication and the faithful transmission of genetic information.

Bile salts and lecithin are responsible for the emulsification of lipids (fats) by breaking down large fat droplets into smaller droplets, which increases the surface area available for enzymes to break down the lipids into their component parts.

Bile salts and lecithin are amphipathic molecules, meaning they have both hydrophobic (water-repellent) and hydrophilic (water-attracting) properties. When added to water, these molecules form micelles - small, spherical structures with their hydrophobic tails on the inside and their hydrophilic heads on the outside.

When bile salts and lecithin come into contact with fat droplets, the hydrophobic tails of the amphipathic molecules are attracted to the surface of the droplets, while the hydrophilic heads remain in the water. This creates a layer of amphipathic molecules around the fat droplet, with the hydrophilic heads facing outward and the hydrophobic tails facing inward towards the fat.

Over time, this layer of amphipathic molecules grows thicker, causing the fat droplet to break up into smaller droplets. This process is called emulsification, and it increases the surface area of the fat droplets, making it easier for digestive enzymes such as lipases to break down the lipids into their component parts.

The resulting smaller fat droplets are then able to pass through the intestinal wall and into the bloodstream, where they can be transported to cells throughout the body and used for energy or other functions.

The accumulation of misfolded proteins in the endoplasmic reticulum (ER) triggers the unfolded protein response (UPR).

The UPR is a cellular stress response mechanism that is activated in response to the presence of misfolded or unfolded proteins in the ER. Its main purpose is to restore ER homeostasis and promote cell survival. When misfolded proteins accumulate, the UPR is initiated to alleviate the stress and restore proper protein folding and ER function. The UPR involves several signaling pathways that regulate gene expression, protein synthesis, and protein degradation. It aims to reduce the load of misfolded proteins, enhance ER protein-folding capacity, and promote the clearance of damaged proteins. The UPR also facilitates the degradation of misfolded proteins through the proteasomal response, in which the proteasome machinery helps eliminate aberrant proteins.
