Fnm 001 Why Eat?

Front 1

This is the feeling you have when hunger goes away. It's important to learn to differentiate between being satisfied and feeling full (which can indicate overeating).

Back 1

Satiety

Front 2

Define 'satiety'

Back 2

The feeling or state of being sated (satisfied to the point where you are no longer hungry (different from full))

Front 3

Which area in the brain responds to changes in circulating metabolic fuels, hormones etc.?

(Main area + two specific areas)

Back 3

Hypothalamus:
- Laterial hypothalamic hunger centre

- Ventro-medial hypothalamic satiety centre

Front 4

A peptide hormone secreted by adipose tissue which acts to regulate long-term appetite and food intake.

Back 4

Leptin

Front 5

What is leptin? (3)

Back 5

A peptide hormone
Secreted by adipose tissue
Which acts to regulate long-term appetite and food intake

Front 6

Which part of the brain is responsible for learned food behaviour?

Back 6

The amygdala (temporal lobe)

Front 7

Circulating peltin is higher/lower in people who are overweight or obese. Why?

Back 7

Higher in overweight people. This is because they have more adipose tissue (leptin is secreted by adipose tissue)

Front 8

Overweight/obese people may have less/more sensitive leptin receptors .

Back 8

Less.

Front 9

As the body manufactures its own amino acids, ingesting food is not necessary for AA production (aside from for metabolic energy/resources to produce said AAs) T/F

Back 9

F - Amino acids are gleaned from food and are required for protein turnover.

Front 10

What is the 'hedonistic' value of food?

Back 10

The pleasure one gets from food (psychological control of appetite)

Front 11

What are the five senses of tase? (Taste buds on the tongue)

Back 11

Salt, sweet, sour, bitter, savoury (umami)

Front 12

'Tending to repel or dissuade'

Back 12

Avesive

Front 13

What does aversive mean?

Back 13

Tending to repel or dissuade

Front 14

Is the innate response of sourness aversive, or pleasurable?

Back 14

Aversive (Tending to repel or dissuade)

Front 15

Is the innate response of bitterness aversive, or pleasurable?

Back 15

Aversive (Tending to repel or dissuade)

Front 16

When it comes to feeding, phsyiological factors can over-ride psychological control T/F

Back 16

F - A variety of foods may stimulate eating despite satiety (e.g. gourmet, glutton, anorexia)

Front 17

What are two possible mechanisms for the role of ATP in membrane transport?

Back 17

Metabolic trapping
Sodium-linked transport and the sodium pump (need to refer to these in lecture notes)

Front 18

Need to know about the role of ATP in muscle contraction

Back 18

.

Front 19

Is the final energy level after a thermoneutral reaction higher or lower than the initial?

Back 19

The same

Front 20

Is the final energy level after an exothermic reaction higher or lower than the initial?

Back 20

Lower

Front 21

Is the final energy level after an endothermic reaction higher or lower than the initial?

Back 21

Higher
